-Subject: [PATCH] MIPS: octeon: Add interface mode detection for Octeon II
-
-Add interface mode detection for Octeon II. This is necessary to detect
-the interface modes correctly on the UBNT E200 board. Code is taken
-from the UBNT GPL source release, with some alterations: SRIO, ILK and
-RXAUI interface modes are removed and instead return disabled as these
-modes are not currently supported.
