2012-04-03e1000e: Guarantee descriptor writeback flush success.Matthew Vick1-0/+17

2012-04-03e1000e: prevent oops when adapter is being closed and reset simultaneouslyBruce Allan2-0/+15
When the adapter is closed while it is simultaneously going through a reset, it can cause a null-pointer dereference when the two different code paths simultaneously cleanup up the Tx/Rx resources.

2012-03-27intel: make wired ethernet driver message level consistent (rev2)stephen hemminger1-1/+6
Dan Carpenter noticed that ixgbevf initial default was different than the rest. But the problem is broader than that, only one Intel driver (ixgb) was doing it almost right. The convention for default debug level should be consistent among Intel drivers and follow established convention.

2012-03-21Merge branch 'kmap_atomic' of git://github.com/congwang/linuxLinus Torvalds1-7/+4
Pull kmap_atomic cleanup from Cong Wang. It's been in -next for a long time, and it gets rid of the (no longer used) second argument to k[un]map_atomic(). Fix up a few trivial conflicts in various drivers, and do an "evil merge" to catch some new uses that have come in since Cong's tree. * 'kmap_atomic' of git://github.com/congwang/linux: (59 commits) feature-removal-schedule.txt: schedule the deprecated form of kmap_atomic() for removal highmem: kill all __kmap_atomic() [[email protected]: highmem: Fix ARM build break due to __kmap_atomic rename] drbd: remove the second argument of k[un]map_atomic() zcache: remove the second argument of k[un]map_atomic() gma500: remove the second argument of k[un]map_atomic() dm: remove the second argument of k[un]map_atomic() tomoyo: remove the second argument of k[un]map_atomic() sunrpc: remove the second argument of k[un]map_atomic() rds: remove the second argument of k[un]map_atomic() net: remove the second argument of k[un]map_atomic() mm: remove the second argument of k[un]map_atomic() lib: remove the second argument of k[un]map_atomic() power: remove the second argument of k[un]map_atomic() kdb: remove the second argument of k[un]map_atomic() udf: remove the second argument of k[un]map_atomic() ubifs: remove the second argument of k[un]map_atomic() squashfs: remove the second argument of k[un]map_atomic() reiserfs: remove the second argument of k[un]map_atomic() ocfs2: remove the second argument of k[un]map_atomic() ntfs: remove the second argument of k[un]map_atomic() ...

Rename e1000e_setup_link() to e1000e_setup_link_generic() to signify the function is used for more than one MAC-family type. The 82571-family has a custom setup_link function which also calls the generic function. The ich8lan-family has a custom function which should just be called via the function pointer.

This enables enabling/disabling reception of the Ethernet FCS. This can be useful when sniffing packets. For e1000e, enabling RXFCS can change the default behaviour for how the NIC handles CRC. Disabling RXFCS will take the NIC back to defaults, which can be configured as part of the module options.

2012-02-13e1000e: cleanup goto statements to exit points without common workBruce Allan8-303/+212
Per ./Documentation/CodingStyle, goto statements are acceptable for the centralized exiting of functions when there are multiple exit points which share common work such as cleanup. When no common work is required for multiple exit points, the function should just return at these exit points instead of doing an unnecessary jump to a centralized return. This patch cleans up the inappropriate use of goto statements, and removes unnecessary variables (or move to a smaller scope) where possible as a result of the cleanups.
