8397f22c34 If we get an interrupt and the interface is down, return before we 
grab the lock.  This should help a tiny bit on machines where unused
if_sis interfaces share IRQ.

7929aa036c Bring in the first chunk of altq driver modifications. This covers the 
following drivers: bfe(4), em(4), fxp(4), lnc(4), tun(4), de(4) rl(4),
sis(4) and xl(4)

More patches are pending on: http://peoples.freebsd.org/~mlaier/ Please take
a look and tell me if "your" driver is missing, so I can fix this.

8c27747768 Vastly improve performance of IRQ handling on stopped interfaces with 
this driver by introducing a flag saying we already stopped the device.

On my Soekris net4801, this took a ping -i 0.001 from spending 80% of
time in interrupt handling to 10% (approx numbers).

This was a particular problem for the net4801 because the tree
interfaces share the same interrupt, but it would be a problem for
any configuration where an unused if_sis interface shares an interrupt
with a busy device.

Other drivers may have similar problems.

48529e81e4 Attempt to get the short cable fix to work better on the if_sis: 
Only do short-cable on revisions that need it.

Move generic initialization before short-cable fix, in order to not
clobber short cable fix register setting.

5120abbfb4 Drop the driver lock around calls to if_input to avoid a LOR when 
the packets are immediately returned for sending (e.g.  when bridging
or packet forwarding).  There are more efficient ways to do this
but for now use the least intrusive approach.

aa8255025a Try to create some sort of consistency in how the routings to find the 
multicast hash are written.  There are still two distinct algorithms used,
and there actually isn't any reason each driver should have its own copy
of this function as they could all share one copy of it (if it grew an
additional argument).

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members 
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

8196d06a54 Examine and record the Silicon Revision Register on NS parts. 
We can't update the device description in attach (why not ?), so
we device_print() what we find.

Conditionalize the short cable fix on this being older than rev 16A.

Call device_printf() when we apply short cable fix.

Include interrupt hold-off setting for rev 16+ under "#ifdef notyet"

The device_printf()'s will go under bootverbose once the various
issues have settled a bit.
