Subject: net: PPP buffer too small for higher speed connections
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=208f2037ae4a2f23fe5f232d25f4030b3a35c3ed;p=deliverable%2Flinux.git

net: PPP buffer too small for higher speed connections

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.
