Subject: network: drop meaningless condition about setting MTU
X-Git-Tag: v249-rc1~76^2~31
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=793117b3fd4c2dbbe9ddd9cfb7795a623379e5b6;p=thirdparty%2Fsystemd.git

network: drop meaningless condition about setting MTU

The condition does not fix infinite loop of interface reset, as the
interface is reset after netlink reply is received, thus setting_mtu is
false.

See also #18738.
