where INTA is asserted while no enabled interrupts are pending, which
cause a continous strean if interrupts with no way to clear it.
Clearing/resetting the enabled interrupt mask in the interrupt handler seems
to workaround this issue (this is what the FreeBSD driver does).
While there properly return 0 if the interrupt was not for us, and explicitely
disable JME_TMCSR in addition to TIMER1 and TIMER2.
panics.
Extract a new function, bnx_add_buf(), from bnx_get_buf().
bnx_add_buf() just tries to add an mbuf to the Rx chain. bnx_get_buf()
tries to allocate an mbuf, first, and then to add the mbuf to the
chain. Use bnx_add_buf() to try to put an mbuf that we took off
of the chain back onto the chain, and use bnx_get_buf() everywhere
else.
This change seems to be in keeping with the author's intent, but
it looks like the code broke at some point.
Thanks to Jarle Greipsland, David Dudley, and others for reporting
this bug and for testing patches.
Use ETHER_ALIGN to calculate number of segments correctly (actually the same way as FreeBSD and OpenBSD do).
Also use ETHER_ALIGN to correctly adjust new mbufs.
This makes the driver finally work. Tested by Jochen Kunz:

ID pair. Misuse of the revision numbers was causing some of the chip
features to be disabled on some integrated Intel chips. So, move the
determination of the features into the bus frontend, where the
vendor/product ID is known. (Note: sc_rev should be removed. The
microcode patch stuff is also busted and needs to be fixed.) Also,
poll the actual flow control status in inphy, rather than making
assumptions.

Unloading doesn't work right in any case -- it doesn't clean up the
sysctl tree, among other things. This code needs Work, but at least
this prevents it crashing randomly due to autounload while X is
running.) Also, fix the dependency list for radeondrm.
