Subject: rtnetlink: do not set notification for tx_queue_len in do_setlink
X-Git-Tag: Ubuntu-5.13.0-19.19~12373^2~39^2
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=2d7f669b42a97022c8c2b6cd86f3990be5fcd1bc;p=mirror_ubuntu-jammy-kernel.git

rtnetlink: do not set notification for tx_queue_len in do_setlink

NETDEV_CHANGE_TX_QUEUE_LEN event process in rtnetlink_event would
send a notification for userspace and tx_queue_len's setting in
do_setlink would trigger NETDEV_CHANGE_TX_QUEUE_LEN.

So it shouldn't set DO_SETLINK_NOTIFY status for this change to
send a notification any more.
