Subject: netdev: Allow netdev_change_seq_changed() to accept const pointers.
X-Git-Tag: v2.3~156
X-Git-Url: http://git.cascardo.eti.br/?a=commitdiff_plain;h=053acb81bc48dcf87d45aa4687a1ec421fbd3581;p=cascardo%2Fovs.git

netdev: Allow netdev_change_seq_changed() to accept const pointers.

This fixes the following warning in the DPDK code.

../lib/netdev-dpdk.c:790:31: error: passing 'const struct netdev *' to
parameter of type 'struct netdev *' discards qualifiers
