When built this fails, thereby for now I've dequeued this from 19.11.7
[ 708s] ../drivers/net/mlx5/mlx5_nl.c: In function ‘mlx5_nl_mac_addr_sync’:
[ 708s] ../drivers/net/mlx5/mlx5_nl.c:685:33: error: ‘mac_addrs’
undeclared (first use in this function); did you mean ‘vec_adds’?
[ 708s] if (rte_is_zero_ether_addr(&mac_addrs[j])) {
[ 708s] ^~~~~~~~~
[ 708s] vec_adds
[ 708s] ../drivers/net/mlx5/mlx5_nl.c:685:33: note: each undeclared
identifier is reported only once for each function it appears in
[ 708s] ninja: build stopped: subcommand failed.
If you have a chance to refresh your backport with the 19.11 codebase
in mind that would be great.
Looking for an updated backport and thanks in advance.
