upstream patch
this is identical to the upstream patch, all I've done is adjust it to apply cleanly to latest 4.7.z (-78.0.17.EL).
Applying only this patch causes several problems: 1. Older drivers can't bring up the link on reboot after using this driver. 2. Other operating systems (windows) can't bring up the link either. 3. Some BIOSen with link-testing features get broken too. Upstream bugzillas: https://bugzilla.redhat.com/show_bug.cgi?id=496964 https://bugzilla.kernel.org/show_bug.cgi?id=13072 https://bugzilla.redhat.com/show_bug.cgi?id=497052 https://bugzilla.redhat.com/show_bug.cgi?id=494844 At least two additional patches are needed: 1. Fix resume from hibernation regression http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=35a7433c789ba6df6d96b70fa745ae9e6cac0038 2. Add phy_power_down parameter, leave phy powered up by default (v2) http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=5a9a8e32ebe269c71d8d3e78f9435fe7729f38e9 Ivan - I've just realized that the patch I proposed here has already been included in 4.8 (-89) as part of your forcedeth 0.62 rebase (bug 479408). I opened this bug the day after it was committed to the 4.8 tree, and unfortunately I'd done my code review a couple days earlier and thus I missed the commit. Apologies for the confusion. However as you noted in comment 5 the 2 additional patches are needed. I plan to provide the customer who reported this w/ a test kernel (-89 + 2 patches from comment 5) to have them test/confirm on their systems which were experiencing problems.
