[PATCH] net/i40evf: remove VF reset during initialization

[PATCH] net/i40evf: remove VF reset during initialization

[beilei.xing]

From: Beilei Xing <beilei.xing@intel.com>

VF reset during initialization will cause PF busy when
multiple VFs request virtual channel message from PF.
VF reset is not necessary during initialization, so
remove it.
