Subject: Deferring transmit completion causes MPE_Ethernet test failures
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=761e6abee32d9b05c91a2d77a0e49dba9eae5e5f;p=people%2Fpauldu%2Fxenvif.git

Deferring transmit completion causes MPE_Ethernet test failures

The test imposes a strict timeout on transmit completion so unfortunately
we have to complete eagerly.
