Subject: bridge/mdb: remove wrong use of NLM_F_MULTI
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=821996795973fd52703c35811a03db9fec1ac141;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

bridge/mdb: remove wrong use of NLM_F_MULTI

NLM_F_MULTI must be used only when a NLMSG_DONE message is sent. In fact,
it is sent only at the end of a dump.

Libraries like libnl will wait forever for NLMSG_DONE.

Fixes: 37a393bc4932 ("bridge: notify mdb changes via netlink")
