Not that I'm aware of.

Here's a raw socket demo that sends and receives raw Ethernet
packets using protocol number 0x55aa on interface eth1. The
file is available at <ftp://ftp.visi.com/users/grante/python/rawDemo.py>.
Last time I looked, the socket module supported raw sockets
under Linux only.
---------------------------------8<---------------------------------
#!/usr/bin/python
import sys
import string
import struct
from socket import *
proto = 0x55aa
s = socket(AF_PACKET, SOCK_RAW, proto)
s.bind(("eth1",proto))
ifName,ifProto,pktType,hwType,hwAddr = s.getsockname()
srcAddr = hwAddr
dstAddr = "\x01\x02\x03\x04\x05\x06"
ethData = "here is some data for an ethernet packet"
txFrame = struct.pack("!6s6sh",dstAddr,srcAddr,proto) + ethData
print "Tx[%d]: "%len(ethData) + string.join(["%02x"%ord(b) for b in ethData]," ")
s.send(txFrame)
rxFrame = s.recv(2048)
dstAddr,srcAddr,proto = struct.unpack("!6s6sh",rxFrame[:14])
ethData = rxFrame[14:]
print "Rx[%d]: "%len(ethData) + string.join(["%02x"%ord(b) for b in ethData]," ")
s.close()
