![]() If the interface is in netmap mode (polling), it is possible for packets with 0 length to be DMAd into memory. While this doesn't seem to happen during normal, interrupt-based traffic, it is highly likely that it is possible for queue overflows to trigger a firmware issue where the RSF function allows zero-length packets to pass during polling mode. We invert the flags as the documentation seems to suggest that setting a '1' in this register would be the default mode, e.g. read a packet from the RX queue only after a complete packet has been written to it, as opposed to operating in cut-through mode, in which the packet is subject to a certain threshold before the MAC actually reads it. The same goes for the TX side. This change seems to drastically increase throughput when in netmap mode. |

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
