[dpdk-dev] [PATCH] i40e: unintended sign extension

Suspicious implicit sign extension: pf->fdir.match_counter_index with type unsigned short (16 bits, unsigned) is promoted in pf->fdir.match_counter_index << 20 to type int (32 bits, signed), then sign-extended to type unsigned long (64 bits, unsigned). If pf->fdir.match_counter_index << 20 is
