Wenjun Wu April 22, 2021, 5:34 a.m. UTC
When resetting VF, VF will issue reset command to PF, wait a
fixed amount of time, and assume VF reset is done. However,
due to the change of dpdk related library content, the original
delay is not enough. When we use DPDK PF instead of kernel PF,
it may cause VF start error.

This patch extend VF reset waiting time from 200ms to 2s so that
VF can start normally when using DPDK PF and DPDK VF.
