Hi, I never used FLOWTABLE, but as I know, when L2 caching was reintroduced the kernel with enabled FLOWTABLE has started crashing almost immediately. glebius@ added workaround in r300854 to prevent the panic. Then we discussed with him that the change in in_pcb.c should be reasonable. And he decided to revert the workaround. Now it seems without r300854 FLOWTABLE isn't usable. --=20 WBR, Andrey V.
