* [netdrvr] myri10ge, ixgbe: remove broken select INTEL_IOATDMAJeff Garzik2008-10-16
| | | | | | | | | | | | We cannot select INTEL_IOATDMA in Kconfig as soon as MYRI10GE or IXGBE is enabled since the former is not available on all architectures. Just use a Kconfig bool {IXGBE,MYRI10GE}_DCA set to =y when DCA support can actually be built.
