for use thoughout the tcp subsystem.
It is IPv4 and IPv6 aware creates a line in the following format:
"TCP: [1.2.3.4]:50332 to [1.2.3.4]:80 tcpflags <RST>"
A "\n" is not included at the end. The caller is supposed to add
further information after the standard tcp log header.
The function returns a NUL terminated string which the caller has
to free(s, M_TCPLOG) after use. All memory allocation is done
with M_NOWAIT and the return value may be NULL in memory shortage
situations.
Either struct in_conninfo || (struct tcphdr && (struct ip || struct
ip6_hdr) have to be supplied.
Due to ip[6].h header inclusion limitations and ordering issues the
struct ip and struct ip6_hdr parameters have to be casted and passed
as void * pointers.
tcp_log_addrs(struct in_conninfo *inc, struct tcphdr *th, void *ip4hdr,
void *ip6hdr)
Usage example:
struct ip *ip;
char *tcplog;
if (tcplog = tcp_log_addrs(NULL, th, (void *)ip, NULL)) {
log(LOG_DEBUG, "%s; %s: Connection attempt to closed port\n",
tcplog, __func__);
free(s, M_TCPLOG);
}

In practice, this bug couldn't manifest, as in the current revision of
the code, no callers pass a NULL rep.

While ng_fec called the ioctl to let interfaces in the bundle know
the list of multicast addresses had changed, it never actually
updated that list on the interfaces in the bundle. Consequently,
the multicast filters could be programmed incorrectly.
if_lagg does this correctly, by maintaining a list of addresses
that it has added to interfaces in the bundle. This commit basically
takes the if_lagg code and adds it to ng_fec.
A version of this patch for RELENG_6 has fixed some problems with
IPv6 ND over ng_fec. This is probably the problem in PR 107523.

defined. This restores the old behavior, and eliminates the
dependency on the kernconf.tmpl when INCLUDE_CONFIG_FILE isn't
included in the kernel config. There were many people in the terminal
room that had almost, but not quite, up-to-date config files that this
helps. I don't know if this is the result of skew among the cvsup
servers, or some other more subtle problem. However, this fix should
work for any config of recent vintage (I tested with the latest, and
one before the recent changes, and eye-balled the intermediate
versions).

The user can enable older PCI-X or PCI adapters using ifconfig.
Secondly, Arthur Hartwig pointed out my MSI change was not working
