Commit "net: dsa: mv88e6xxx: fix > in-band AN link establishment" addresses this. > > - The dts configured dissimilar link modes at each end of the host to > switch link; the host was configured using a fixed link (so has no > in-band status) and the switch was configured to expect in-band > status. > > With both issues fixed, the regression is resolved. > > Fixes: 34b5e6a33c1a ("net: dsa: mv88e6xxx: Configure MAC when using fixed link") > Reported-by: Martin Rowe <martin.p.rowe@...il.com> > Signed-off-by: Russell King <rmk+kernel@...linux.org.uk> Applied and queued up for -stable, thanks.
