Commit Message

Cui, LunyuanX Sept. 6, 2019, 11:47 a.m. UTC 
  The original issue was that the last queue could not
be mapped to the interrupt vector, so the last queue
could not receive the package in the interrupt mode.
This patch fixes the issue.

Fixes: d6bde6b5eae9 ("net/avf: enable Rx interrupt")
