Non-linear legacy RQ: validate MTU for robustness, build the linear part of SKB over the first hardware fragment (instead of copying the packet headers), adjust headroom calculations to allow enabling headroom in the non-linear mode (useful for XDP multi buffer). b. XDP: do the XDP program test before function call, optimize parameters of mlx5e_xdp_handle. 2) From Rongwei Liu, DR, reduce steering memory usage Currently, mlx5 driver uses mlx5_htbl/chunk/ste to organize steering logic. However there is a little memory waste. This update targets to reduce steering memory footprint by: a. Adjust struct member layout. b. Remove duplicated indicator by using simple functions call. With 500k TX rules(3 ste) plus 500k RX rules(6 stes), these patches can save around 17% memory. 3) Three cleanup commits at the end of this series. =================== Signed-off-by: David S.
