ok, that is strange. do you see any performance differences without
TX_SW_CFG regs? iperf test is a good pointer.
this was a problem on xiaomi mini with old DD trunk builds on 4.4
kernel and LEDE builds from last year. i ain't got no chance to try
this on 18.06. which device you tried this on? if ipa/ilna it might
make no difference
