Miller Subject: [PATCH] igb: correct hardware type (i210/i211) check in igb_loopback_test()
In the original code ... if ((adapter->hw.mac.type == e1000_i210) || (adapter->hw.mac.type == e1000_i210)) { ... the second check of 'adapter->hw.mac.type' is pointless since it tests for the exact same value as the first.
After reading through a few other parts of the driver I believe that the second check was actually intended to check for 'e1000_i211' rather than 'e1000_i210', but I admit that I'm not certain so someone with more knowledge about this driver should ACK the patch before it gets merged.
Unfortunately I have no hardware to actually test this on, so it is compile tested only.

ACK.
Good catch. Thanks Jesper!
