Subject: nfp: devlink: initialize the devlink port attribute "lanes"
X-Git-Tag: v5.11.21~54
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=781950db7ef34ac9861b7b133bc3ac74a4caa51d;p=thirdparty%2Fkernel%2Fstable.git

nfp: devlink: initialize the devlink port attribute "lanes"

[ Upstream commit 90b669d65d99a3ee6965275269967cdee4da106e ]

The number of lanes of devlink port should be correctly initialized
when registering the port, so that the input check when running
"devlink port split <port> count <N>" can pass.

Fixes: a21cf0a8330b ("devlink: Add a new devlink port lanes attribute and pass to netlink")
