Subject: [PATCH 02/30] igb: fix vf lookup
|
|
|
|
commit 0629292117572a60465f38cdedde2f8164c3df0b upstream.
|
|
|
|
Recent addition of code to find already allocated VFs failed to take
|
|
account that systems with 2 or more multi-port SR-IOV capable controllers
|
|
might have already enabled VFs. Make sure that the VFs the function is
|
|
finding are actually subordinate to the particular instance of the adapter
|
|
that is looking for them and not subordinate to some device that has
|
|
previously enabled SR-IOV.
|
|
|
|
This is applicable to 3.2+ kernels.
