RealTek changed TX descriptor format for later controllers so these controllers require MSS configuration in different location of TX descriptor. TSO is enabled by default for controllers that use new descriptor format. For old controllers, TSO is still disabled by default due to broken frames under certain conditions but users can enable it. Special thanks to Hayes Wang at RealTek. r217832: Disable TSO for all Realtek controllers. Experimentation showed RTL8111C generated corrupted frames where TCP option header was broken. All other sample controllers I have did not show such problem so it could be RTL8111C specific issue. Because there are too many variants it's hard to tell how many controllers have such issue. Just disable TSO by default but have user override it. Revision Changes Path 1.95.2.67 +16 -20 src/sys/dev/re/if_re.c 1.67.2.34 +2 -0 src/sys/pci/if_rlreg.h
