RTL8126A and RTL8127A share most of the register layouts and quirks with
RTL8125 series, but require explicit desc type and CRC-drop setup during
init.
This patch adds PCI IDs and MAC versions. RTL8126A is 0x66 and RTL8127A
is 0x6e. And RTL8127A requires Tx Desc V3 format and an additional RADM
FIFO protection configuration according to vendor driver.
