From ff645bec523819fa4d28d7e0de7d998e3edb0c57 Mon Sep 17 00:00:00 2001 From: Michael Chan <mchan@broadcom.com> Date: Thu, 21 Apr 2005 17:09:53 -0700 Subject: [TG3]: Workaround 5752 A0 chip ID The 5752 A0 chip ID is wrong in hardware. The simplest way to workaround it is to change it to the correct value in tp->pci_chip_rev_id. This way, it is easier to check for the ASIC_REV_5752 in the rest of the driver.
