Expose system level ixgbe sysctls. Device level sysctls are already exposed as dev.ix. Fixing the case where number of queues for igb is auto-tuned and hw.igb.num_queues does not return current/updated value.

the vectors we requested, and fall back to MSI when not, also release any allocated resources before the fallback.

Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI command register. The lazy BAR allocation code in FreeBSD sometimes disables this bit when it detects a range conflict, and will re-enable it on demand when a driver allocates the BAR. Thus, the bit is no longer a reliable indication of capability, and should not be checked. This results in the elimination of a lot of code from drivers, and also gives the opportunity to simplify a lot of drivers to use a helper API to set the busmaster enable bit. This changes fixes some recent reports of disk controllers and their associated drives/enclosures disappearing during boot.

Correct the Intel network driver module builds. They were not defining INET or INET6, and in the case of ixgbe this will cause a panic in the TSO setup code, but in all cases the ioctl behavior is different, this change makes the module and static consistent. Approved by: re
