Extend mlx5 debugfs support to present Software Steering resources:
dr_domain including it's tables, matchers and rules.
The interface is read-only. While dump is being presented, new steering
rules cannot be inserted/deleted.

The steering information is dumped in the CSV form with the following
format:

    <object_type>,<object_ID>, <object_info>,...,<object_info>

This data can be read at the following path:

    /sys/kernel/debug/mlx5/<BDF>/steering/fdb/<domain_handle>

Example:

    # cat /sys/kernel/debug/mlx5/0000:82:00.0/steering/fdb/dmn_000018644
    3100,0x55caa4621c50,0xee802,4,65533
    3101,0x55caa4621c50,0xe0100008

Changes in V2:
 - Reduce temp hex buffer size and avoid unnecessary memset
 - Use bin2hex() instead of DIY loop
 - Don't check debugfs functions return values

1GbE Intel Wired LAN Driver Updates 2021-12-29

Ruud Bos says:

The igb driver provides support for PEROUT and EXTTS pin functions that
allow adapter external use of timing signals. At Hottinger Bruel & Kjaer we
are using the PEROUT function to feed a PTP corrected 1pps signal into an
FPGA as cross system synchronized time source.

Support for the PEROUT and EXTTS SDP functions is currently limited to
i210/i211 based adapters. This patch series enables these functions also
for 82580/i354/i350 based ones. Because the time registers of these
adapters do not have the nice split in second rollovers as the i210 has,
the implementation is slightly more complex compared to the i210
implementation.

The PEROUT function has been successfully tested on an i350 based ethernet
adapter. Using the following user space code excerpt, the driver outputs a
PTP corrected 1pps signal on the SDP0 pin of an i350:

    struct ptp_pin_desc desc;
    memset(&desc, 0, sizeof(desc));
    desc.index = 0;
    desc.func = PTP_PF_PEROUT;
    desc.chan = 0;
    if (ioctl(fd, PTP_PIN_SETFUNC, &desc) == 0) {
        struct timespec ts;
        if (clock_gettime(clkid, &ts) == 0) {
            struct ptp_perout_request rq;
            memset(&rq, 0, sizeof(rq));
            rq.index = 0;
            rq.start.sec = ts.tv_sec + 1;
            rq.start.nsec = 500000000;
            rq.period.sec  = 1;
            rq.period.nsec = 0;
            if (ioctl(fd, PTP_PEROUT_REQUEST, &rq) == 0) {
                /* 1pps signal is now available on SDP0 */
            }
        }
    }

The added EXTTS function has not been tested. However, looking at the data
sheets, the layout of the registers involved match the i210 exactly except
for the time registers mentioned before. Hence the almost identical
implementation.

This issue was also reported since 2017 in the thread [1],
unfortunately, the issue was still can be reproduced after fixing
DCCP.

The ipv4_mib_exit_net is called before tcp_sk_exit_batch when a net
namespace is destroyed since tcp_sk_ops is registered befrore
ipv4_mib_ops, which means tcp_sk_ops is in the front of ipv4_mib_ops
in the list of pernet_list. There will be a use-after-free on
net->mib.net_statistics in tw_timer_handler after ipv4_mib_exit_net
if there are some inflight time-wait timers.

This bug is not introduced by commit f2bf415c ("mib: add net to
NET_ADD_STATS_BH") since the net_statistics is a global variable
instead of dynamic allocation and freeing. Actually, commit
61a7e260 ("mib: put net statistics on struct net") introduces
the bug since it put net statistics on struct net and free it when
net namespace is destroyed.

Moving init_ipv4_mibs() to the front of tcp_init() to fix this bug
and replace pr_crit() with panic() since continuing is meaningless
when init_ipv4_mibs() fails.

udpgso_bench_tx call setup_sockaddr() for dest address before
parsing all arguments, if we specify "-p ${dst_port}" after "-D ${dst_ip}",
then ${dst_port} will be ignored, and using default cfg_port 8000.

This will cause test case "multiple GRO socks" failed in udpgro.sh.

Setup sockaddr after parsing all arguments.
