socket in kernel mode

Hello,everyone, does anyone know how to use the socket in kernel mode? In my block device driver I need to communicate with another computer in the network. Thanks, any help will be appreciated.

Standard 2.4.x kernel tree
Take a look at khttpd, /usr/src/net/khttpd, kernel mode http server.
In case of Redhat 7.2. /usr/src/net/tux, Redhat kernel mode http server.

Both of them are acctully are more than just k sockets, they showed how k socket can be used with user mode socket.  

you can allocate a skbuff, and fill it with what you should send throught network, and call the function dev_queue_xmit(skb); to send the buffer to NIC
