[dpdk-dev] [PATCH] i40e: fix the write flush in vf driver

[Jingjing Wu]

For i40e vf driver, should use I40EVF_WRITE_FLUSH to flush
configuration but not I40E_WRITE_FLUSH. This patch fixed this issue.

Fixes: be6c228d4da3 (i40evf: support Rx interrupt)

For i40e vf driver, should use I40EVF_WRITE_FLUSH to flush configuration but 
not I40E_WRITE_FLUSH. This patch fixed this issue.
