thorpej 10c252ba47 Changes to allow the IPv4 and IPv6 layers to align headers themseves, ... as necessary: * Implement a new mbuf utility routine, m_copyup(), is is like m_pullup(), except that it always prepends and copies, rather than only doing so if the desired length is larger than m->m_len. m_copyup() also allows an offset into the destination mbuf, which allows space for packet headers, in the forwarding case. * Add *_HDR_ALIGNED_P() macros for IP, IPv6, ICMP, and IGMP. These macros expand to 1 if __NO_STRICT_ALIGNMENT is defined, so that architectures which do not have strict alignment constraints don't pay for the test or visit the new align-if-needed path. * Use the new macros to check if a header needs to be aligned, or to assert that it already is, as appropriate. Note: This code is still somewhat experimental. However, the new code path won't be visited if individual device drivers continue to guarantee that packets are delivered to layer 3 already properly aligned (which are rules that are already in use).		2002-06-30 22:40:32 +00:00
