[PATCH 0/3] sis190 gigabit fixes(bug 9735,11149) and new phy - 2nd ed

[Riccardo Ghetta]

Patches updated as requested. This time at least the day should be correct :-)

First patch is just cosmetic, to make easier to identify newer phys.
Second adds a new phy found on my Asus F5Sr laptop. It's an Atheros/Attansic
chip, but I wasn't able to identify it further.
The third patch should enable sis191 adapters to connect at Gb speeds
(at least, it does on my laptop). Also bumps the version number.
The gigabit check is a remix of SiS own GPL driver and forcedeth.

Riccardo Ghetta (3):
  sis190: better message on unknown PHY
  sis190: add new phy found on asus F5Sr laptop
  sis190: fix gigabit negotiation

[PATCH 3/3] sis190: fix gigabit negotiation

[Riccardo Ghetta]

Fixes an initialization error; the chip negotiates gigabit, but
the driver mistakenly handled it as 100Mb.
Changes based on both SiS own GPL driver and forcedeth.
Hopefully should fix
