alc 630d0d0838 Update the Tigon 1 and 2 driver to use the sf_buf API for implementing
zero-copy receive of jumbo frames.  This eliminates the need for the
jumbo frame allocator implemented in kern/uipc_jumbo.c and sys/jumbo.h.
Remove it.

Note: Zero-copy receive of jumbo frames did not work without these changes;
I believe there was insufficient locking on the jumbo vm object.
