https://git.stealer.net/cgit.cgi/user/sven/linux.git/atom?h=v4.9.2802016-08-15T17:55:53Zpptp: Refactor the struct and macros of PPTP codes2016-08-15T17:55:53ZGao Fengfgao@ikuai8.com2016-08-12T16:30:48Zurn:sha1:03459345bc00da70a35fa39bcfcf13d779097074
1. Use struct gre_base_hdr directly in pptp_gre_header instead of
duplicated members;
2. Use existing macros like GRE_KEY, GRE_SEQ, and so on instead of
duplicated macros defined by PPTP;
3. Add new macros like GRE_IS_ACK/SEQ and so on instead of
PPTP_GRE_IS_A/S and so on;

rps: Inspect PPTP encapsulated by GRE to get flow hash2016-08-11T00:22:14ZGao Fengfgao@ikuai8.com2016-08-09T04:38:24Zurn:sha1:ab10dccb11608b96b43b557c12a5ad867723e503
The PPTP is encapsulated by GRE header with that GRE_VERSION bits
must contain one. But current GRE RPS needs the GRE_VERSION must be
zero. So RPS does not work for PPTP traffic.
In my test environment, there are four MIPS cores, and all traffic
are passed through by PPTP. As a result, only one core is 100% busy
while other three cores are very idle. After this patch, the usage
of four cores are balanced well.
