Hi,

t4_link_start() was completely misnamed. It does _not_ start up the

this routine to t4_link_l1c

eBPF programs attached to ingress and egress qdiscs see inconsistent skb->data.
For ingress L2 header is already pulled, whereas for egress it's present.
This is known to program writers which are currently forced to use
BPF_LL_OFF workaround.
Since programs don't change skb internal pointers it is
allow programs read/write skb->mark, tc_index fields and

The tcp_read_sock() interface dequeues skbs and gives them to the
caller's callback function for processing. This interface can avoid
data copies since the caller accesses the skb instead of using its own
receive buffer.

sockets. T
Use a function pointer to abstract tcp_read_sock()-like functions. For
TCP this function will be tcp_read_sock(). For AF_VSOCK it will be

Until now, mlx5_query_port_ptys always queried port number one.
Added new argument in the function's prototype so we can also query
the second port. This will be needed when thr helper will be invoked

Ethernet functionality is only available when working in ISSI > 0 mode.
Previously, the IB driver wasn't ready to work on that mode, and hence

driver were disallowed by Kconfigs.

Move the vport header file to be under include/linux/mlx5, such that
the mlx5 IB can use it as well.
Also add nic_ prefix to the vport NIC commands to differeniate between
HCA vport commands and NIC vport commands.

I deferred considering the ECN implications of doing so. The code to
start PRR was based on tcp_enter_cwr()/tcp_init_cwnd_reduction(), save
that both of these functions ensure a call to tcp_ecn_queue_cwr().
The upcoming patch set instead exports tcp_
We don't need to return the IPv6 address hash as part of flow keys.
In general, using the IPv6 address hash is risky in a hash value
since the underlying use of xor provides no entropy. If someone
really needs the hash value they can get it from the full IPv6
addresses in flow keys (e.g. from flow_

This patch set adds new fields to the flow_keys structure and hashes
over these fields to get a better flow hash. In particular, these
patches now include hashing over the full IPv6 addresses in order

same hash. The new input also includ
This patch changes flow hashing to use jhash2 over the flow_keys
structure instead just doing jhash_3words over src, dst, and ports.
This method will allow us take more input into the hashing function
so that we can include full IPv6 addresses, VLAN, flow labels etc.

This patch adds full IPv6 addresses into flow_keys and uses them as
input to the flow hash function. The implementation supports either
IPv4 or IPv6 addresses in a union, and selector is used to determine
