From 095946758305cbef0391a557fe02adc755b4a60a Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 12 Apr 2011 19:50:15 +0000 Subject: [PATCH] solos: various upstreamed solos patches These patches were submitted to netdev and will likely be out in 2.6.38.3. In the meantime, they're needed in 2.6.37.6.
