Subject: [PATCH] ixgbe: Remove out-of-tree references

The module parameters FdirMode, FdirPballoc, AtrSampleRate, or Node are
not available in the in-kernel driver, only in Intel's out-of-tree
SourceForge driver. Remove these from the kernel documentation.

Remove reference to Intel affinity script. Move max_vfs to tidy up.
