If you don't want to do that, should there be a constant similar to ETHER_ADDR_LEN that is suitable for IB to avoid hardcoding '20' in ndp? Here is the similar code from arp (which ndp probably should adopt in some fashion): if (sdl->sdl_alen) { if ((sdl->sdl_type == IFT_ETHER || sdl->sdl_type == IFT_L2VLAN || sdl->sdl_type == IFT_BRIDGE) && sdl->sdl_alen == ETHER_ADDR_LEN) printf("%s", ether_ntoa((struct ether_addr *)LLADDR(sdl))); else { int n = sdl->sdl_nlen > 0 ? sdl->sdl_nlen + 1 : 0; printf("%s", link_ntoa(sdl) + n); } } else printf("(incomplete)"); > The diffs are actually quite small when you eliminate ofed diffs.

Just applying the diffs is probably fine. Also, at some point I would probably like to rename intr_drain() or hide it in some way so that only ofed uses it. FreeBSD drivers should drain interrupt handlers, not IRQs. I realize the ofed Linux compat shims are stuck with that interface, but for FreeBSD drivers I want a proper interface. -- John Baldwin
