The C define appears to be called:

	ETHTOOL_A_PHY_UPSTREAM_INDEX,		/* u32 */

either it needs to gain the PHY_ or the spec needs to lose the phy-,
otherwise C code gen gets upset:

ethtool-user.c:689:10: error: ‘ETHTOOL_A_PHY_UPSTREAM_PHY_INDEX’ undeclared here (not in a function); did you mean ‘ETHTOOL_A_PHY_UPSTREAM_INDEX’?
  689 |         [ETHTOOL_A_PHY_UPSTREAM_PHY_INDEX] = { .name = "upstream-phy-index", .type = YNL_PT_U32, },
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |          ETHTOOL_A_PHY_UPSTREAM_INDEX

Unfortunately ethtool in the in-between state where we can auto-gen
user space code (or rather most of it) but the uAPI header is not
auto-generated so we need to take extra care to keep things in sync :(
