f54ddc3c17 Add a function to lookup bridge members by struct ifnet * and use 
it at all call sites that have such a pointer readily available.
This avoids unnecessary strcmp()s in critical paths, and removes
some XXX comments.

63a1f2ed02 Delete IFM_IEEE80211_IBSS [ibss] and IFM_IEEE80211_IBSSMASTER [ibss-master] 
from media options, since IEEE80211_ADHOC [adhoc] is already defined for
IBSS.  Instead, [ibss] is assigned as an alias for IEEE80211_ADHOC.

c59bd1a572 In ether_output(), don't bother calling memcpy() to plop the ethertype

assign the value, and on others, do an inline 2 byte copy.

c00fa8dfd9 avoid swapping endian of ip_len and ip_off on mbuf, to meet with M_LEADINGSPACE 
optimization made last year.  should solve PR 17867 and 10195.

provide IP_HDRINCL variant that does not swap endian.

6675196afb Make tun interfaces perform auto-creation. This means that if a 
program opens /dev/tun# and tun# has not been SIOCIFCREATE'd already,
it will be SIOCIFCREATE'd automatically.  FreeBSD's tun interfaces
behave in a somewhat similar fashion.

a180cee23b Pool deals fairly well with physical memory shortage, but it doesn't 
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.

Implement a secondary connection-reestablishement mode, which is only

In this mode we retry (infrequently) forever, until adminstrator stops
us (by "ifconfig ppppoe0 down"). XXX - need to display this mode in
pppoectl.

It is now possible to pull the DSL modems plug for say 15 minutes, plug

b7c46d6199 use ALIGNED_POINTER() instead of ALIGN(). 
The type of ALIGN() is vary on architecture and casting pointer to u_int
is incorrect for MI code.
Since the code is to make sure aligned access to IP header and requires
bcopy if the test fails.  So the performance implication is not necessary
and we can use ALIGNED_POINTER() here.

4d51fe368b change the meaning of ifnet.if_lastchange to meet RFC1573 ifLastChange. 
follows BSD/OS practice and ucd-snmp code (FreeBSD does it for specific
interfaces only).

was: if_lastchange get updated on every packet transmission/receipt.
now: if_lastchange get updated when IFF_UP is changed.

4f7cad1c02 On a non-simplex interface, check incoming multicast (this catches 
the broadcast case as well) to see if they came from us, and drop
them if they did.

This fixed IPv6 DAD on non-simplex interfaces, e.g. the Seeq 8003
found on my SGI Indy.

ca4d373730 Implement support for IP/TCP/UDP checksum offloading provided by 
network interfaces.  This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us.  In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software.  This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.

We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.

Note: hardware-assisted checksumming defaults to "off".  It is
enabled with ifconfig(8).  See the manual page for details.

Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.

a6e732946b Add an Ethernet option bit for master mode (for 1000baseTX, the link 
master provides the clock -- this is normally the switch, but if you
are doing back-to-back NICs, you need to tell one side to be the master).

b5b75a7d19 Add an in-kernel PPPoE (ppp over ethernet, RFC 2516) implementation, 
based on the existing net/if_spppsubr.c stuff.

While there are completely userland (bpf based) implementations available,
those have a vastly larger per packet overhead thus causing major CPU
overhead and higher latency. On an i386 base router, running a 486DX at 50MHz
my line (768kBit/s downstream) was limited to something (varying) between 10
and 20 kByte/s effective download rate. With this implementation I get full
bandwidth (~85kByte/s).

This is client side only. Arguably the right way to add full PPPoE support
(including server side) would be a variation of the ppp line discipline and
appropriate modifications to pppd. I promise every help I can give to anyone
doing that - but I needed this realy fast. Besids, on low memory NAT boxes
with typically a single PPPoE connection, this implementation is more
lightweight than a pppd based one, which nicely fits my needs.
