Subject: i40e/base: enhance adminq init and ASQ send
X-Git-Tag: spdx-start~9202
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c3a39d517a03b6289a94c0f02cd8dd0bf28d47e2;p=dpdk.git

i40e/base: enhance adminq init and ASQ send

The timeout of ASQ command is enlarged from 100 ms to 250 ms to
wait longer time for the response. nvm_busy is not needed anymore.
Also nvm_release_on_done and nvmupd_state will be set during
adminq init.
