From f85b60710571b37293d2233933b76e2aa3db5635 Mon Sep 17 00:00:00 2001 From: Rafal Jaworowski Date: Thu, 27 Dec 2007 18:19:02 +0100 Subject: Introduce new eth_receive routine The purpose of this routine is receiving a single network frame, outside of U-Boot's NetLoop(). Exporting it to standalone programs that run on top of U-Boot will let them utilise networking facilities. For sending a raw frame the already existing eth_send() can be used. The direct consumer of this routine is the newly introduced API layer for external applications (enabled with CONFIG_API).
