c4df070a57 selftests: hw-net: rss-input-xfrm: try to enable the xfrm at the start
The test currently SKIPs if the symmetric RSS xfrm is not enabled
by default. This leads to spurious SKIPs in the Intel CI reporting
results to NIPA.

Testing on CX7:

 # ./drivers/net/hw/rss_input_xfrm.py
  TAP version 13
  1..2
  ok 1 rss_input_xfrm.test_rss_input_xfrm_ipv4 # SKIP Test requires IPv4 connectivity
  # Sym input xfrm already enabled: {'sym-or-xor'}
  ok 2 rss_input_xfrm.test_rss_input_xfrm_ipv6
  # Totals: pass:1 fail:0 xfail:0 xpass:0 skip:1 error:0

 # ethtool -X eth0 xfrm none

 # ./drivers/net/hw/rss_input_xfrm.py
  TAP version 13
  1..2
  ok 1 rss_input_xfrm.test_rss_input_xfrm_ipv4 # SKIP Test requires IPv4 connectivity
  # Sym input xfrm configured: {'sym-or-xor'}
  ok 2 rss_input_xfrm.test_rss_input_xfrm_ipv6
  # Totals: pass:1 fail:0 xfail:0 xpass:0 skip:1 error:0

d74cd9a02f selftests: drv-net: Make command requirements explicit
Make require_cmd() calls explicit about whether commands are needed
locally, remotely, or both.
Since require_cmd() defaults to local=True, tests should explicitly set
local=False when commands are only needed remotely.

- socat: Set local=False since it's only needed on remote hosts.
- iperf3: Use single call with both local=True and remote=True since
  it's needed on both hosts.

This avoids unnecessary test failures when commands are missing locally
but available remotely where actually needed, and consolidates a
duplicate require_cmd() call into single call that checks both hosts.

c1b27f0695 netlink: specs: define input-xfrm enum in the spec
Help YNL decode the values for input-xfrm by defining
the possible values in the spec. Don't define "no change"
as it's an IOCTL artifact with no use in Netlink.

With this change on mlx5 input-xfrm gets decoded:

 # ynl --family ethtool --dump rss-get
 [{'header': {'dev-index': 2, 'dev-name': 'eth0'},
   'hfunc': 1,
   'hkey': b'V\xa8\xf9\x9 ...',
   'indir': [0, 1, ... ],
   'input-xfrm': {'sym-or-xor'},                         <<<
   'flow-hash': {'ah4': {'ip-dst', 'ip-src'},
                 'ah6': {'ip-dst', 'ip-src'},
                 'esp4': {'ip-dst', 'ip-src'},

07caaf875c netlink: specs: ethtool: replace underscores with dashes in names
We're trying to add a strict regexp for the name format in the spec.
Underscores will not be allowed, dashes should be used instead.
This makes no difference to C (codegen replaces special chars in names)
but gives more uniform naming in Python.

c76bab22e9 selftests: drv-net: rss_input_xfrm: Check test prerequisites before running
Ensure the following prerequisites before executing the test:
1. 'socat' is installed on the remote host.
2. Python version supports socket.SO_INCOMING_CPU (available since v3.11).

Skip the test if either prerequisite is not met.

da87cabaf8 selftests: drv-net-hw: Add a test for symmetric RSS hash
Add a selftest that verifies symmetric RSS hash is working as intended.
The test runs iterations of traffic, swapping the src/dst UDP ports, and
verifies that the same RX queue is receiving the traffic in both cases.
