[ Upstream commit f286dd8eaad5a2758750f407ab079298e0bcc8a5 ]
Use correct type to check for all-mask exact match IP addresses.
Fixes following sparse warnings due to big endian value checks against 0xffffffff in is_addr_all_mask(): cxgb4_filter.c:977:25: warning: restricted __be32 degrades to integer cxgb4_filter.c:983:37: warning: restricted __be32 degrades to integer cxgb4_filter.c:984:37: warning: restricted __be32 degrades to integer cxgb4_filter.c:985:37: warning: restricted __be32 degrades to integer cxgb4_filter.c:986:37: warning: restricted __be32 degrades to integer
