MFC 1.35:

2005-01-29T23:36:29Z

Use ng_callout() and ng_uncallout() instead of home-grown implementation. Tested by: Savchuk Taras Reviewed by: archie Approved by: julian (mentor)

MFC 1.34:

2004-09-10T06:16:34Z

Increase PPTP_MAX_TIMEOUT up to 3 seconds. 10 proved too much for high packet loss links, and 1 second appeared to be too small for high latency links. Approved by: re (scottl)

Switch to using C99 sparse initialisers for the type methods array.

Should make no binary difference. Submitted by: Gleb Smirnoff Reviewed by: Harti Brandt MFC after: 1 week

Add 'enableWindowing' configuration knob to the ng_pptpgre(4) netgraph node.

Lower the maximum ACK timeout for GRE packets from 10 to 1 second.

2003-11-18T20:43:23Z

In practice it seems that in situations of high packet loss the ACK timeout seems to hit this maximum (perhaps inappropriately, but the estimation algorithm is not perfect, so apparently it happens). In any case, 10 seconds is way too high a value so lower to 1 second. MFC after: 3 days

Don't use ovbcopy().

2003-04-04T12:12:34Z

Back out M_* changes, per decision of the TRB.

2003-02-19T05:47:46Z

Approved by: trb

Remove M_TRYWAIT/M_WAITOK/M_WAIT. Callers should use 0.

2003-01-21T08:56:16Z

Merge M_NOWAIT/M_DONTWAIT into a single flag M_NOWAIT.

o Untangle the confusion with the malloc flags {M_WAITOK, M_NOWAIT} and

2002-12-19T22:58:27Z

the mbuf allocator flags {M_TRYWAIT, M_DONTWAIT}. o Fix a bpf_compat issue where malloc() was defined to just call bpf_alloc() and pass the 'canwait' flag(s) along. It's been changed to call bpf_alloc() but pass the corresponding M_TRYWAIT or M_DONTWAIT flag (and only one of those two). Submitted by: Hiten Pandya (hiten->commit_count++)
