Subject: bnx2x: Send update-svid ramrod with retry/poll flags enabled
Patch-mainline: v4.20
Git-commit: 9061193c4ee065d3240fde06767c2e06ec61decc
References: bsc#1104402 FATE#325899
Driver sends update-SVID ramrod in the MFW notification path.
If there is a pending ramrod, driver doesn't retry the command
and storm firmware will never be updated with the SVID value.
The patch adds changes to send update-svid ramrod in process context with
retry/poll flags set.
