drain routines are done by swi_net, which allows for better queue control
at some future point. Packets may also be directly dispatched to a netisr
instead of queued, this may be of interest at some installations, but
currently defaults to off.

o fix #ifdef typo
o must use "bounce functions" when dispatched from the protosw table
don't know how this stuff was missed in my testing; must've committed
the wrong bits

from the KAME IPsec implementation, but with heavy borrowing and influence
of openbsd. A key feature of this implementation is that it uses the kernel
crypto framework to do all crypto work so when h/w crypto support is present
IPsec operation is automatically accelerated. Otherwise the protocol
implementations are rather differet while the SADB and policy management
code is very similar to KAME (for the moment).
Note that this implementation is enabled with a FAST_IPSEC option. With this
you get all protocols; i.e. there is no FAST_IPSEC_ESP option.
FAST_IPSEC and IPSEC are mutually exclusive; you cannot build both into a
single system.
This software is well tested with IPv4 but should be considered very
experimental (i.e. do not deploy in production environments). This software
does NOT currently support IPv6. In fact do not configure FAST_IPSEC and
INET6 in the same system.
