igb: fix ethtool offline test
A bug was introduced with the following patch: Commmit bdbc063129e811264cd6c311d8c2d9b95de01231 Author: Eric Dumazet <eric.dumazet@gmail.com> igb: Add support for byte queue limits. The ethtool offline tests will cause a perpetual link flap, this is because the tests also need to account for byte queue limits (BQL). CC: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Tested-by: Jeff Pieper <jeffrey.e.pieper@intel.com>
