CVS commit: src/sys/netinet

[David Young <dyoung%netbsd.org@localhost>]

Module Name:    src
Committed By:   dyoung
Date:           Fri Jul 28 17:06:59 UTC 2006

Modified Files:
        src/sys/netinet: ip_gre.c

Log Message:
Fix mtod() usage.  If we will write to the mbuf data, check whether
the data is read-only/shared and call m_pullup().  Otherwise,
extract a const pointer to the mbuf data.

XXX I should extract a new macro, M_WRITABLE(m, len), that is true
if m has len consecutive writable bytes at its front.

KNF slightly.

Use bpf_mtap_af().
