Hauke Mehrtens 438718b5fb kernel: bump 5.4 to 5.4.114
Removed because in upstream*
  mvebu/patches-5.4/319-ARM-dts-turris-omnia-configure-LED-2--INTn-pin-as-interrupt-pin.patch

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().

Compile-tested on: x86/64, armvirt/64, ath79/generic
Runtime-tested on: x86/64, armvirt/64, ath79/generic

Subject: [RFC net-next 7/7] net: dsa: mv88e6xxx: Request assisted learning on CPU port
Date: Sat, 16 Jan 2021 02:25:15 +0100

While the hardware is capable of performing learning on the CPU port,
it requires alot of additions to the bridge's forwarding path in order
to handle multi-destination traffic correctly.
Until that is in place, opt for the next best thing and let DSA sync
the relevant addresses down to the hardware FDB.
