Subject: [net] netxen: further p3 updates for rhel5.5
Message-id: <20091130184826.32699.8491.sendpatchset@file.bos.redhat.com>
Patchwork-id: 21550
O-Subject: [rhel 5.5 patch] NetXen P3 - further updates from upstream.
Bugzilla: 542746

BZ 542746
These updates are taken from the 2.6.32-rc8 and net-next-2.6 trees
and backported to rhel 5.5. They apply and build cleanly with 2.6.18-175.
Tested at QLogic / NetXen.
commit eb6d02133cf5451fece3a37ccccf2ce7c09a09c1
netxen: remove PCI IDs of CNA device
Remove PCI vendor and device IDs for QLE8240 and QLE8242
CNA devices. CNA devices will have separate driver.
commit 5d09e534bbb94e1fdc8e4783ac822bc172465a91
netxen : fix BOND_MODE_TLB/ALB mode.
o Along with netdev->perm_addr, mac address will be
maintained in device private structure.
o Device limitation: We need to set mac address when ever
interface comes up.
In ALB/TAL mode, bonding driver calls set_mac for all slave with bond mac address.
But bonding driver set netdev->dev_addr field to its original value,
after enslaving interfaces.
When ever active slave changes, it swap dev_addr of inactive slave with active.
Yet it doesn't notify driver about change in netdev->dev_addr.
As netxen driver need to set mac addr when ever interface comes up,
it can't rely on netdev->dev_addr field. Specially in case of bonding mode ALB/TLB.
commit a7483b0afa63e851c4438ddda8934a296851f1de
netxen: fix promisc for NX2031.
Kernel crashes, if promisc mode set without disabling rx queue.
Before changing mode in NX2031 chip, wait till rx queue drains.
commit 5d521fd36de4e61ab16a358df54c5babe153396c
netxen: fix memory initialization
Avoid resetting memory during initialization, skip this memory
block during driver probe.
commit c70948105d4f057b90d4a587246565782e51ed35
netxen: update version to 4.0.65
commit 7e8e5d9718744b817bfea6f020586d7035cc89f4
netxen: module firmware hints
Add MODULE_FIRMWARE hints for various firmware file types,
required by different chip revisions.
commit c25c0b9b33f681972e0b2abc96b9debdd1ef32a5
netxen: update module info
Update module info with QLogic signature.
commit f0e08fac06596a760f074c08521550d93b96336e
netxen: add PCI IDs for new chip
Add PCI vendor and device IDs for QLE8240 and QLE8242
CNA devices.
commit a9ac07deeb4b880aea3eaccf7ec913ac902aeef9
netxen: refactor indirect register access
Refactor code to calculate and set indirect access
window for control registers in 2MB address space
(NX3031 or newer). Use void __iomem * data type for
absolute pci addresses.
commit f50330f90b9aa42b7058650ce66b85f1b443ab11
netxen: support for new firmware file format
Add support for extracting firmware from a unified
file format which embeds firmware images for all chip
revisions. Fallback to orginal file formats if new
image is not found.
commit 0531d7b85177cda05f574ddf0aa4b25050159101
netxen: fix builds for SYSFS=n or MODULES=n
When CONFIG_MODULES=n:
drivers/net/netxen/netxen_nic_main.c:2751: error: dereferencing pointer to incomplete type
drivers/net/netxen/netxen_nic_main.c:2764: error: dereferencing pointer to incomplete type
Also needs addition of <linux/sysfs.h> for sysfs function prototypes or
stubs when CONFIG_SYSFS=n.
commit 0dc6d9cbe7df4d2c3cdf17cd2f78733102b0fea6
netxen: avoid undue board config check
Old code assumed board config version in the flash to be 1.
When this will get changed by tools, driver just refuses to
attach. This is unnecessary since driver does not have to
parse board config structure directly (maintained by firmware).
commit ff8a306d63a01f15f166039de94c448c76140d1d
netxen: fix tx timeout handling on firmware hang
Clear NX_RESETING bit in netxen_tx_timeout_task() so that
the firmware watchdog task can catch need_reset request
from tx timeout.
commit 8bee0a91dd2f472d51dc107288c988ae0a0f371a
netxen: fix i2c init
Avoid resetting subsys ID in i2c block. Also remove duplicate
check for address tranlsation error.
commit 7194660da7a6d119fa469bd11b58e7367a5cbdf4
netxen; update version to 4.0.62
commit caa2dd53bc2f9c44938f2f261ebe15e2f26cc51e
netxen: sysfs control for auto firmware recovery
Firmware hang detection and recovery (reset) need to
be disabled for diagnostic tools, which can run
some disruptive tests.
This adds a driver level control to turn off this
feature by diag tools.
commit 7cecdca133ea9791adce21819b9e9eed79045f23
netxen: fix error codes in for tools access
Use -EIO or -EINVAL as error codes, these can get passed up
to applications (tools).
commit 6abb4b83eac25d91f6de834e97b2ea38e979575b
netxen: onchip memory access change
Add support for different windowing scheme for on chip
memory in future chip revisions. This is required by
diagnostic tools.
commit 0be367bd5d10634c0836f57a684432fee935d929
netxen: reset sequence changes
Future revisions need different chip reset sequence
and firmware initialization.
Also clean up some never used debug code.
commit fb1f6a4378fe211d8c1397311d26e747e5ec61c5
netxen: 128 memory controller support
Future revisions of the chip have 128 bit memory
transactions. Require drivers to implement rmw
in case of sub-128 bit accesses by driver. This
is mostly used by diagnostic tools.
commit 0a2aa440603f27ad40bcc14806f4d87aabbd8a0f
netxen: defines for next revision
commit 70f9cf8951e5253cfef821f8dcb92f6fc3af50c6
netxen: add sysfs entries for diag tools
Add sysfs entries to enable register and memory access
for diagnostic tools.
commit f03b0ebd8e7132bd9adb41348070813feb280300
netxen: separate register and memory access lock
Since register and onboard memory access has separate
window registers, they need not be kept under same lock.
Also, memory is always accessed from process context
(mostly for firmware init and diagnostic tools).
commit 907fa1201c76f426a13bdff5be2747fb62c2353f
netxen: annotate register windowing code
Use common variables crb_win, ocm_win for all revisions of chip.
commit 47abe35610cbbfb3cc92847efdf588a8be1f5ebc
netxen: add access to on chip memory for tools
Add access to on chip memory, this is used by
debug and diagnostic tools only.
commit 1f5e055db369a5d1c74174571585a4ec2e6c40fb
netxen: remove sub 64-bit mem accesses
Sub 64-bit / unaligned access to oncard memory was only used
by old diagnostic tools, causes some intermittent issues when
memory controller agent is used. The new access method was
added by commit ea6828b8aa3a8ebae8d7740f32f212ba1d2f0742
("netxen: improve pci memory access"). Firmware init anyway
uses 8-byte strides.
This also fixes address/offset calculation for NX2031 context
memory (SIU). For NX3031, SIU uses same register offsets
as packet memory (MIU).
commit fa3ce355c1bf1a83b843420228202fd6f8023ad3
netxen: bridged mode optimizations
When the interface is put in bridged mode, destination mac
addresses are unknown to firmware. So packets take a slow
path (lower priority) in firmware reducing performance.
Firmware can cache limited number of remote unicast mac
addresses for certain interval, if "dynamic mac learning"
mode is enabled.
Driver needs to enable this "mac learning" mode in firmware.
Currently this is done through net device class sysfs entry,
possibly this can also be done upon netlink notifications to
from bridge.
commit 71fb62fb6dd4ed95e6f0240a2c627df396d9d057
netxen: fix pci bar mapping
Use resource_size_t for PCI resource remapping instead
of unsigned long. Physical addresses can exceed range of
long data type (e.g with PAE).
commit fa9859ef2bb56d876db53c258001af115f38a272
netxen: Fix Unlikely(x) > y
The closing parenthesis was not on the right location.
commit 07653aa3afe7b74cbddfe3bca82a898c413855b1
netxen: fix firmware init after resume
After successful firmware init, return instead of
falling to error path (leading to detach) after
resuming to D0 state. This was broken in recent
firmware reset rehaul.
commit a598ae177a11ebae065e20059d9bc63a5da4ccc3
netxen: fix minor tx timeout bug
Fix minor bug in netdev tx timeout handling which could
always lead to firmware reset instead of pci function reset.
netxen_nic_reset_context() requires __NX_RESETTING bit
cleared.
