Because nfe(4) hardware doesn't support SG on Rx path, supporting jumbo frame requires very large contiguous kernel memory(i.e. several mega bytes). In case of lack of contiguous kernel memory that allocation request may always fail. However nfe(4) can operate on normal sized MTU frames, so go ahead and just disable jumbo frame support. While I'm here add a new tunable "hw.nfe.jumbo_disable" to disable jumbo frame support. In nfe_poll, make sure to invoke correct Rx handler. Approved by: re (kensmith) |
