Subject: bonding: enable netpoll without checking link status
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ceda86a108671294052cbf51660097b6534672f5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

bonding: enable netpoll without checking link status

Only slaves that are up should transmit netpoll frames, so there is no
need to check to see if a slave is up before enabling netpoll on it.
This resolves a reported failure on active-backup bonds where a slave
interface is down when netpoll was enabled.
