e1000: FIX: fix wrong txdctl threshold bitmasks
Threshold bitmasks for prefetch, host and writeback were clearing bits that they were not supposed to. The leftmost 2 bits in the byte for each threshold are reserved. Signed-off-by: Bruce Allan <bruce.w.allan@intel.com> Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com>
