This is the first usage of the new bpf_prog ID. It is for
reporting the ID of a xdp_prog through netlink.
It rides on the existing IFLA_XDP. This patch adds IFLA_XDP_PROG_ID

It starts with changing the generic_xdp first. After that,

Yeah, this is basically mostly copy-pasted from the sboot code,
would need some cleaning up.
I've been playing more a little with other bits of the hardware,
writing some test fw from scratch, mostly without using the builtin
rom (except for interrupts).

To build samples/bpf on MIPS we need to avoid some inline asm that

Looking at the code, it seems that arm64 had the same problem and
avoided it by defining the header guard symbol. This approach does
not scale, so I invented a preprocessor define to identify the case of

When building for the eBPF target archecture. Inline asm cannot be
used as MIPS instructions are fundamentally incompatible with eBPF
bytecode. The preprocessor symbol __EMITTING_BPF__ is used to gate
the inclusion of inline asm in constructs used the by the BPF
programs.

Driver needs to wait for all resources to return from FW before it can send
the FUNC_CLOSE ramrod.

Whenever firmware indicates that there's an async indication it needs
to handle, there's a switch-case where the right functionality is called
based on function's personality and information.

Once we have iWARP support, the qede portion of the qedr<->qede would
serve all the RDMA protocols - so rename the file to be appropriate
to its function.

iWARP would require the chains to allocate/free their PBL memory
independently, so add the infrastructure to provide it externally.

This series focuses on RDMA in general with emphasis on required changes
toward adding iWARP support. The vast majority of the changes introduced
are in qed/qede, with a couple of small changes to qedr
[mentioned below].
The infrastructure changes:

Similarly to how cross-chip VLAN works, define a bitmap of multicast
group members for a switch, now including its DSA ports, so that
multicast traffic can be sent to all switches of the fabric.
A switch may drop the frames if no user port is a member.
This brings support for multicast in a multi

Sample BPF program, tcp_clamp_kern.c, to demostrate the use
of setting the sndcwnd clamp. This program assumes that if the
first 5.5 bytes of the host's IPv6 addresses are the same, then
the hosts are in the same datacenter and sets sndcwnd clamp to
100 packets, SYN and SYN-ACK RTOs to 10ms and sen
This patch contains a BPF program to set initial receive window to

be done after doing appropriate checks that indicate the hosts are

Added support for calling a subset of socket setsockopts from
BPF_PROG_TYPE_SOCKET_OPS programs. The code was duplicated rather
than making the changes to call the socket setsockopt function because
the changes required would have been larger.
The ops supported are:
SO_RCVBUF
SO_SNDBUF
SO_MA
