From cd027a5433d66734097adbd9d262c203471102a3 Mon Sep 17 00:00:00 2001 From: Jacek Kalwas Date: Thu, 12 Apr 2018 12:03:13 -0700 Subject: udp: enable UDP checksum offload for ESP In case NIC has support for ESP TX CSUM offload skb->ip_summed is not set to CHECKSUM_PARTIAL which results in checksum calculated by SW. Fix enables ESP TX CSUM for UDP by extending condition with check for NETIF_F_HW_ESP_TX_CSUM.
