update ATM driver. (base version: midway.c 1.67 --> 1.68)

Browse Source 
several new features are added:
	- support vc/vp shaping
	- support pvc shadow interface

code cleanup:
	- remove WMAYBE related code.  ENI WMAYBE DMA doen't work.
	- remove updating if_lastchange for every packet.
	- BPF related code is moved to midway.c as it should be.
	  (bpfwrite should work if atm_pseudohdr and LLC/SNAP are
	  prepended.)
	- BPF link type is changed to DLT_ATM_RFC1483.
	  BPF now understands only LLC/SNAP!! (because bpf can't
	  handle variable link header length.)
	  It is recommended to use LLC/SNAP instead of NULL
	  encapsulation for various reasons.  (BPF, IPv6,
	  interoperability, etc.)

the code has been used for months in ALTQ and KAME IPv6.

OKed by phk long time ago.
