X-Git-Tag: v2.6.15~28 X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=68ca243dd1dc90bd42bae3945e804c1042584920;p=~emulex%2Finfiniband.git [SERMOUSE]: Sun mice speak 5-byte protocol too. Noticed by Christophe Zimmerman, this explains the slow mouse movement with 2.6.x kernels. And checking the 2.4.x drivers/sbus/char/sunmouse.c driver shows we always used a 5-byte protocol with Sun mice in the past. I have no idea how the 3-byte thing got into the 2.6.x driver, but it's surely wrong. Signed-off-by: David S.
