Driver was contributed in 2008. The following reasons lead to the removal: - This driver generates maintenance workload for itself and for API wext - wext is deprecated and only used by two wireless drivers in mainline kernel - no progress changing to mac80211 - This driver has a maximum 54MBit/s as it supports only 802.11 b/g. - Using this hardware is security wise not state of the art as WPA3 is not supported. The longterm kernels will still support this hardware for years. Find further discussions and history in the Link below. Link: https://lore.kernel.org/linux-staging/a7eb3db4-ad0d-451a-9106-90d481bd3231@gmail.com/ Signed-off-by: Philipp Hortmann <philipp.g.hortmann@gmail.com> --- Only compile tested. Tested a rebased version of this patch on the Playstation 3. Used T2 Linux with Kernel 6.12.5 to test the Ethernet connection.
