* pending-5.4/479-mtd-spi-nor-add-eon-en25qh64.patch
Some bigger changes were done to this feature and we did not port this patch yet:
* hack-5.4/207-disable-modorder.patch
This depends on BOOTMEM which was removed from the kernel, this needs some bigger changes:
* hack-5.4/930-crashlog.patch
A different version of the FPU disable patch was merged upstream, OpenWrt needs some adaptations.
* pending-5.4/304-mips_disable_fpu.patch
- no crashlog support yet as a required file got deleted upstream
- Removed patch below, which is now seen as a recursive dependency [1]
- Removed patch below due to build error [2]
- fix still required to avoid identical function def [3]
- Fixes included from Blocktrron
- Fixes included from Chunkeey
- Fix included from nbd regarding "dst leak in Flow Offload"

-ctinfo is a new tc filter action module. It is designed to restore -information contained in firewall conntrack marks to other packet fields -and is typically used on packet ingress paths. At present it has two -independent sub-functions or operating modes, DSCP restoration mode & -skb mark restoration mode. - -The DSCP restore mode: - -This mode copies DSCP values that have been placed in the firewall -conntrack mark back into the IPv4/v6 diffserv fields of relevant -packets. - -The DSCP restoration is intended for use and has been found useful for -restoring ingress classifications based on egress classifications across -links that bleach or otherwise change DSCP, typically home ISP Internet -links. Restoring DSCP on ingress on the WAN link allows qdiscs such as -but by no means limited to CAKE to shape inbound packets according to -policies that are easier to set & mark on egress. - -Ingress classification is traditionally a challenging task since -iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT -lookups, hence are unable to see internal IPv4 addresses as used on the -typical home masquerading gateway. Thus marking the connection in some -manner on egress for later restoration of classification on ingress is -easier to implement. - -Parameters related to DSCP restore mode: - -dscpmask - a 32 bit mask of 6 contiguous bits and indicate bits of the -conntrack mark field contain the DSCP value to be restored. - -statemask - a 32 bit mask of (usually) 1 bit length, outside the area -specified by dscpmask. This represents a conditional operation flag -whereby the DSCP is only restored if the flag is set. This is useful to -implement a 'one shot' iptables based classification where the -'complicated' iptables rules are only run once to classify the -connection on initial (egress) packet and subsequent packets are all -marked/restored with the same DSCP. A mask of zero disables the -conditional behaviour ie. the conntrack mark DSCP bits are always -restored to the ip diffserv field (assuming the conntrack entry is found -& the skb is an ipv4/ipv6 type) - -e.g. dscpmask 0xfc000000 statemask 0x01000000 - -|----0xFC----conntrack mark----000000---| -| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0| -| DSCP | unused | flag |unused | -|-----------------------0x01---000000---| - | | - | | - ---| Conditional flag - v only restore if set -|-ip diffserv-| -| 6 bits | -|-------------| - -The skb mark restore mode (cpmark): - -This mode copies the firewall conntrack mark to the skb's mark field. -It is completely the functional equivalent of the existing act_connmark -action with the additional feature of being able to apply a mask to the -restored value. - -Parameters related to skb mark restore mode: - -mask - a 32 bit mask applied to the firewall conntrack mark to mask out -bits unwanted for restoration. This can be useful where the conntrack -mark is being used for different purposes by different applications. If -not specified and by default the whole mark field is copied (i.e. -default mask of 0xffffffff) - -e.g. mask 0x00ffffff to mask out the top 8 bits being used by the -aforementioned DSCP restore mode. - -|----0x00----conntrack mark----ffffff---| -| Bits 31-24 | | -| DSCP & flag| some value here | -|---------------------------------------| - | - | - v -|------------skb mark-------------------| -| | | -| zeroed | | -|---------------------------------------| - -Overall parameters: - -zone - conntrack zone - -control - action related control (reclassify | pipe | drop | continue | -ok | goto chain <CHAIN_INDEX>) - -Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk> -Reviewed-by: Toke Høiland-Jørgensen <toke@redhat.com> -Acked-by: Cong Wang <xiyou.wangcong@gmail.com> -Signed-off-by: David S.

Similar call sequence holds for phylink_stop(), only in the reverse -order.
