Subject: Spidernet remove rxramfull tasklet
X-Git-Tag: v2.6.21-rc1~92^2~31^2~87
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=75856175c26f89198ec64eb2480ed00c4a39a5d6;p=linux-2.6

Spidernet remove rxramfull tasklet

Get rid of the rxramfull tasklet, and let the NAPI poll routine
deal with this situation. (The rxramfull interrupt is simply
stating that the h/w has run out of room for incoming packets).
