not the current BPF device should report locally generated packets or not.
This allows sniffing applications to see only packets that are not generated
locally, which can be useful for debugging bridging problems, or other
situations where MAC addresses are not sufficient to identify locally
sourced packets. Default to true for this flag, so as to provide existing
behavior by default.
Introduce two new ioctls, BIOCGSEESENT and BIOCSSEESENT, which may be used
to manipulate this flag from userland, given appropriate privilege.
Modify bpf.4 to document these two new ioctl arguments.

this version include:
- Support for version 2.x firmware (2.42 or later recommended). This
means we are the only open-source driver supporting these adapters.
This code has only been tested on a Digital KZPCA adapter in an Alpha
system, but is believed to be correct. NOTE: EISA adapters are not
yet supported.
- Support the BIOS/Firmware initialisation handshake protocol. This
allows the driver to bring the card up to operational state even if
the BIOS can't be run (eg. if it's an x86 BIOS in an Alpha system).
- A working command pasthrough interface. This allows a user-space
configuration tool (under development) to issue arbitrary commands
to the controller or to devices in the system.

to devsw(), which caused a page fault.

And stop calling DEVICE_NOMATCH at probe repeatedly. This stops the

This makes it possible to handle the done queue even when the end of tail
TD has ended up on the done queue as well (the xfer in this case is NULL

the unwary if the code were called in slightly different ways.
1) In ufs_bmaparray() the code for calculating 'runb' will stop one block
short of the first entry in an indirect block. i.e. if an indirect block
contains N block numbers b[0]..b[N-1] then the code will never check if
b[0] and b[1] are sequential. For reference, compare with the equivalent
code that deals with direct blocks.
2) In ufs_lookup() there is an off-by-one error in the test that checks
if dp->i_diroff is outside the range of the the current directory size.
This is completely harmless, since the following while-loop condition
'dp->i_offset < endsearch' is never met, so the code immediately
does a second pass starting at dp->i_offset = 0.
3) Again in ufs_lookup(), the condition in a sanity check is wrong
for directories that are longer than one block. This bug means that
the sanity check is only effective for small directories.
