[PATCH ethtool v2 0/2] netlink: require a value for hds-thresh and the TDR parameters

[Dave Seddon <dave.seddon.ca@gmail.com>]

hds-thresh (-G) and first, last, step and pair (--cable-test-tdr) take
a value but leave min_argc at 0, so a missing value prints
"invalid value '(null)'" instead of "no value for parameter". Each
patch sets min_argc to 1 for one command.

Changes in v2:
- Split into one patch per command, each with its own Fixes tag
  (Andrew Lunn).
- v1: https://lore.kernel.org/netdev/20261102023919.1472495-1-dave.seddon.ca@gmail.com/

Checked by hand on a build of each patch on bae2dbd: the parameters
it covers print "no value for parameter", the others are unchanged.
make check passes.

Claude found the issue while porting the code from C to Go, and drafted
the patches; I reviewed them and take responsibility for them.
