Of 4 boards in our automated test system 2 do not have reliable networking with the default TX delay of 0x0. Increasing to 0x1 seems to make things reliable on all 4 boards. Some previous ad-hpoc tests with tx delay set to 0, 1, 2 and 3 on one of the problematic boards showed: 0: mw.l 0x1c20164 0x006 1 -- t/o in 4/5 tftp runs 1: mw.l 0x1c20164 0x406 1 -- t/o in 1/5 tftp runs 2: mw.l 0x1c20164 0x806 1 -- t/o in 1/5 tftp runs 3: mw.l 0x1c20164 0xc06 1 -- t/o many times in first tftp run For 0, 1 and 2 "t/o" means one or two "T" glitches in the download, but it did complete. For 3 those were basically continuous and it couldn't complete. tftp was of a 16M initrd.
