[PATCH 1/4] net/i40e: fix AVX-512 pointer copy on 32-bit

2024-09-06 Thread Bruce Richardson
The size of a pointer on 32-bit is only 4 rather than 8 bytes, so copying 32 pointers only requires half the number of AVX-512 load store operations. Fixes: 5171b4ee6b6b ("net/i40e: optimize Tx by using AVX512") Cc: sta...@dpdk.org Signed-off-by: Bruce Richardson --- drivers/net/i40e/i40e_rxtx_
