[PATCH net-next v2 11/14] net: qede: use extack in qede_parse_flow_attr()

Asbjørn Sloth Tønnesen
2024-05-08T14:34:36Z

Convert qede_parse_flow_attr() to take extack,
and drop the edev argument.

Convert DP_NOTICE calls to use NL_SET_ERR_MSG_* instead.

Pass extack in calls to qede_flow_parse_{tcp,udp}_v{4,6}().

In calls to qede_parse_flow_attr(), if extack is
unavailable, then use NULL for now, until a
subsequent patch makes extack available.

Only compile tested.
