Resending. commit 89681d3655f27d758537ae01a02d500deee1acd6 Author: Mohsin Shaikh Date: Thu Apr 9 12:19:45 2020 +0800 net/mlx5: Use open/read/close for reading ib stat fgets(3)/fread(3)/fscanf(3) etc. use mmap(2)/munmap

[dpdk-dev] [PATCH] net/mlx5: use open/read/close for reading ib stat

fgets(3)/fread(3)/fscanf(3) etc. use mmap(2)/munmap(2) which leads to TLB shootdown interrupts to all dpdk app cores including RX cores. This can cause packet drops. Use read(2)/write(2) instead. Bugzilla ID: 440 Cc: sta...@dpdk.org Signed-off-by: Mohsin Shaikh --- drivers/net/mlx5
