====================
net: Add GRO support for UDP encapsulating protocols
This series adds GRO handlers for protocols that do UDP encapsulation, with the
intent of being able to coalesce packets which encapsulate packets belonging to
the same TCP session.
For GRO purposes, the destination UDP port takes the role of the ether type
field in the ethernet header or the next protocol in the IP header.
The UDP GRO handler will only attempt to coalesce packets whose destination
port is registered to have gro handler.
The patches done against net-next 75e4364f67 "net: stmmac: fix NULL pointer
dereference in stmmac_get_tx_hwtstamp"
Or.
v4 --> v5 changes:
- followed Eric's directives to avoid using atomic get/put ops on the
udp gro receive and complete callbacks and instead keep the rcu_read_lock
when calling the next handler on the chain.
v3 --> v4 changes:
- applied feedback from Tom on some micro-optimizations that save
branches and goto directives in the udp gro logic
- applied feedback from Eric on correct RCU programming for the
add/remove flow of the upper protocols udp gro handlers
v2 --> v3 changes:
- moved to use linked list to store the udp gro handlers, this solves the
problem of consuming 512KB of memory for the handlers.
- use a mark on the skb GRO CB data to disallow running the udp gro_receive twice
on a packet, this solves the problem of udp encapsulated packets whose inner VM
packet is udp and happen to carry a port which has registered offloads - and flush it.
- invoke the udp offload protocol registration and de-registration from the vxlan driver
in a sleepable context

This change adds a parameter for the Synopsys 10/100/1000
stmmac Ethernet driver to configure the maximum frame
size supported by the EMAC driver. Synopsys allows the FIFO
sizes to be configured when the cores are built for a particular
device, but do not provide a way for the driver to read
information from the device about the maximum MTU size
supported as limited by the device's FIFO size.

Smatch complains because we are using an untrusted index into the
rxrpc_acks[] array. It's just a read and it's only in the debug code,
but it's simple enough to add a check and fix it.

Some ipv6 protocols cannot handle ipv4 addresses, so we must not allow
connecting and binding to them. sendmsg logic does already check msg->name
for this but must trust already connected sockets which could be set up
for connection to ipv4 address family.
Per-socket flag ipv6only is of no use here, as it is under users control
by setsockopt.

Doesn't bring much, but also doesn't hurt us to fix 'em:
1) In tpacket_rcv() flush dcache page we can restirct the scope
for start and end and remove one layer of indent.
2) In tpacket_destruct_skb() we can restirct the scope for ph.
3) In alloc_one_pg_vec_page() we can remove the NULL assignment
and change spacing a bit.
