Subject: [PATCH] myri10ge: remove broken select INTEL_IOATDMA from Kconfig
We cannot select INTEL_IOATDMA in Kconfig as soon as MYRI10GE is
enabled since the former is not available on all architectures.
Just use a Kconfig bool MYRI10GE_DCA set to =y when DCA support
can actually be built in myri10ge (when DCA is enabled, except
if MYRI10GE=y and DCA=m).
