DEV_ADD_PACK(9) 					      Network device support						   DEV_ADD_PACK(9)

NAME
       dev_add_pack - add packet handler

SYNOPSIS
       void dev_add_pack(struct packet_type * pt);

ARGUMENTS
       pt
	   packet type declaration

DESCRIPTION
       Add a protocol handler to the networking stack. The passed packet_type is linked into kernel lists and may not be freed until it has been
       removed from the kernel lists.

       This call does not sleep therefore it can not guarantee all CPU's that are in middle of receiving packets will see the new packet type
       (until the next received packet).
