Revision 1.6.4.1, Sun Jul 23 03:49:32 2000 UTC (23 years, 8 months ago) by itojun
Branch: netbsd-1-5
CVS Tags: netbsd-1-5-RELEASE, netbsd-1-5-PATCH003, netbsd-1-5-PATCH002, netbsd-1-5-PATCH001, netbsd-1-5-BETA2, netbsd-1-5-BETA, netbsd-1-5-ALPHA2
Changes since 1.6: +2 -2 lines

pullup from main trunc (approved by releng-1-5)

raise MSIZE from 128 to 256.
- for sizeof(void *) == 8 arch, this is mandatory.  MHLEN is too small
  already (less than 80) and there are chances for unwanted packet loss due
  to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
  (even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
  extension header)

portmasters: if your arch chokes with the change (high memory usage or
whatever), please backout the change for your arch.
