Subject: [PATCH v3 1/2] realtek: convert to per-chip mask
The previous HW_REVID macro did not make identifiers more readable
(compared to hex values like 0x12345678) and only allowed for one static
mask. To make it easier to update the chips list, let's use similar
structures as r8169 and remove HW_REVID.
Names are removed and separated from the table and separated because the
mac_version does not have to be unique.
While at it, change "RTL-xxxx" to "RTLxxxx" to match the names of
Realtek and r8169 driver. Besides that, the only output change is when
a chip is not recognized in which case "TxConfig" is now mentioned
instead of "mask". Since the mask can be anything, the displayed word is
not masked either.
