Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Cross-merge networking fixes after downstream PR (net-6.18-rc6).

No conflicts, adjacent changes in:

drivers/net/phy/micrel.c
  96a9178a29a6 ("net: phy: micrel: lan8814 fix reset of the QSGMII interface")
  61b7ade9ba8c ("net: phy: micrel: Add support for non PTP SKUs for lan8814")

and a trivial one in tools/testing/selftests/drivers/net/Makefile.
