drivers/net: delete all code/drivers depending on CONFIG_MCA
The support for CONFIG_MCA is being removed, since the 20 year old hardware simply isn't capable of meeting today's software demands on CPU and memory resources. This commit removes any MCA specific net drivers, and removes any MCA specific probe/support code from drivers that were doing a dual ISA/MCA role. Cc: "David S. Miller" <davem@davemloft.net> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Cc: netdev@vger.kernel.org Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
