Subject: linux-atm: Solos card requires explicit buffer size to br2684ctl
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7b7242564ad77f6ad1fe00e61a2a6929e3334c23;p=openwrt%2Fstaging%2Fdangole.git

linux-atm: Solos card requires explicit buffer size to br2684ctl

The default send buffer size of 8192 potentially can run past the end of the buffer (skb) and trash memory.
Explicitly setting a limit is required.
