From fe442683853a2c0863b700acc4328b4d73090206 Mon Sep 17 00:00:00 2001 From: Inaky Perez-Gonzalez Date: Wed, 22 Apr 2009 16:53:08 -0700 Subject: wimax/i2400m: generate fake source MAC address with random_ether_addr() The WiMAX i2400m driver needs to generate a fake source MAC address to fake an ethernet header (for destination, the card's MAC is used). This is the source of the packet, which is the basestation it came from. The basestation's mac address is not usable for this, as it uses its own namespace and it is not always available. Currently the fake source MAC address was being set to all zeros, which was causing trouble with bridging. Use random_ether_addr() to generate a proper one that creates no trouble.
