From 463d413cb7dcd5509bc01e1108c2e2dcf8104683 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Mon, 21 Jan 2013 19:13:26 -0500 Subject: [PATCH] drivers/net: delete old x86 variant of the seeq8005 driver The last update to the Ethernet HowTo (over 10 years ago) listed this: ------------------------ SEEQ 8005 Status: Obsolete, Driver Name: seeq8005 There is little information about the card included in the driver, and hence little information to be put here. If you have a question, you are probably best trying to e-mail the driver author as listed in the source. It was marked obsolete as of the 2.4 series kernels. ------------------------ If it was obsolete over a decade ago, the situation can not have improved with the passage of time, so let us act on that. Even with today's improved search engines, I was unable to locate any real meaningful information on the ISA implementation of this rare chip. There are ARM and SGI variants of the driver in tree, but they do not depend on the original x86 driver source or header file. We leave those non-x86 drivers to be deleted by the arch maintainers when they decide to expire those legacy platforms as a whole.
