From 0d2873df15a9dad7a4a3012870836bb51216324c Mon Sep 17 00:00:00 2001 From: John Audia Date: Tue, 27 Apr 2021 18:18:36 -0400 Subject: kernel: bump 5.4 to 5.4.114 Manually rebased* generic/backport-5.4/700-v5.5-net-core-allow-fast-GRO-for-skbs-with-Ethernet-heade.patch Added new backport* generic/backport-5.4/050-gro-fix-napi_gro_frags-Fast-GRO-breakage-due-to-IP-a.patch All others updated automatically. The new backport was included based on this[1] upstream commit that will be mainlined soon. This change is needed because Eric Dumazet's check for NET_IP_ALIGN (landed in 5.4.114) causes huge slowdowns on drivers which use napi_gro_frags().
