FreeBSD repository version of this file and the isdn4bsd version,
adopt those changes from the i4b version that make this file
BSD-version independent. I attempted to avoid uglifying this file too
much, thus deviated a little from the i4b version (and hope they will
adopt the changes, too).
The diffs mostly concentrate on:
. #include differences between the systems
. different callout handling between FreeBSD vs. Net/OpenBSD
. interface naming (Net/OpenBSD store the ASCII name including the
unit # in struct ifnet, FreeBSD only the name)
. use of random() in FreeBSD vs. time-based pseudo-randomization in
Net/OpenBSD (for loopback detection ad CHAP challenges -- i
assume at least OpenBSD could also benefit from random(), but that's
the way i've got this file)
. interface address list elements are named a little differently
between FreeBSD and Net/OpenBSD
I attempted to segregate those compat fixes from other code fixes and
enhancements.
