NetBSD/sys/dev/pci/if_lmcvar.h
itojun 477b193d09 support T1 card (LMC1200) properly. PR 12331 (patch from openbsd).
change DLT type to cisco HDLC, as lmc driver is hardwired to cisco HDLC
on driver attach.  XXX we may need to revisit this, as if_spppsubr may want
to alter this later.

* The 21040 has a stupid restriction in that the receive

* headers are not a multiple of longwords in size this forces

* data to be longword aligned, we need to copy it after it has
* been DMA'ed in our memory.
*
* Since we have to copy it anyways, we might as well as allocate
* dedicated receive space for the input. This allows to use a
* small receive buffer size and more ring entries to be able to
* better keep with a flood of tiny Ethernet packets.
*
* The receive space MUST ALWAYS be a multiple of the page size.
* And the number of receive descriptors multiplied by the size
* of the receive buffers must equal the recevive space. This
* is so that we can manipulate the page tables so that even if a
* packet wraps around the end of the receive space, we can
* treat it as virtually contiguous.
*
* The above used to be true (the stupid restriction is still true)
* but we gone to directly DMA'ing into MBUFs (unless it's on an
* architecture which can't handle unaligned accesses) because with
* 100Mb/s cards the copying is just too much of a hit.
