From 2d3b2e4427e2d74085bd2c17ffd737875871c983 Mon Sep 17 00:00:00 2001 From: Bob Pearson Date: Thu, 17 Jun 2021 23:57:43 -0500 Subject: [PATCH] RDMA/rxe: Fix redundant skb_put_zero rxe_init_packet() in rxe_net.c calls skb_put_zero() to reserve space for the payload and zero it out. All these bytes are then re-written with RoCE headers and payload. Remove this useless extra copy.
