Subject: Felix's patch backported my software blink emulation,
X-Git-Tag: v2.6.38-rc1-1~15
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=53f02799156e702e88bbf970797792dbfde99bba;p=~emulex%2Ffor-vlad%2Fcompat.git

Felix's patch backported my software blink emulation,
but if the kernel is 2.6.25 or newer we can also try
the HW offload first.
