Tried to remove the csum features by commenting out ifp->if_capabilities |= IFCAP_TXCSUM | IFCAP_RXCSUM; ifp->if_hwassist = AXE_CSUM_FEATURES; (lines 855 and 856 in /usr/src/sys/dev/usb/net/if_axe.c) and rebuild the module. This does remove RXCSUM and TXCSUM from options and behaves the same as disabling the features with ifconfig (i.e. does not work) 10.0-CURRENT r248351 Hope someone can help me... Spil.
