217712 Fix a couple of incorrect variable names in the sysctl code.
217713 - Panic on the 82598 adapter due to reading FCOE registers that don't exit
- Make phy detection dynamic so adapters that support multiple types of
media can be properly identified by the interface layer
- Performance patch to the flow director (ixgbe_atr) code
- Fix intermittent data corruption on the 82599
- Add missing support code for buffer size and descriptors when doing
jumbo frames, also add 16K cluster support.

217796 Add missing case for Direct Attach 82598 in the dynamic phy detection
217797 Performance: don't run flow control shared code if nothing has changed
