I ended up doing quite a bit more cleanup to the l2_packet wrapper
interface and left support for both types in l2_packet_linux.c. Anyway,
the end result should be the same as far as wpa_supplicant with
l2_packet_linux.c is concerned, i.e., SOCK_DGRAM is used instead of
SOCK_RAW. All the changes are now in my CVS repository and will be
included in the next release assuming no major problems gets reported.
