Subject: [PATCH 1/5]net: PPP buffer too small for higher speed connections

From: fangxiaozhi <huananhu@...wei.com>
1. This patch is based on the kernel of 2.6.32-rc7 
2. In this patch, we enlarge the out buffer size to optimize the upload speed for the ppp connection. Then it can support the upload of HSUPA data cards.
