The driver provides a DMA buffer to the firmware when it requests port

the driver allocates the DMA buffer the first time it requests stats

primary/secondary processes are involved. For example, the following
sequence crashes the secondary process.

1. Start a primary app that does not call rte_eth_stats_get()
2. dpdk-procinfo -- --stats

dpdk-procinfo crashes while trying to allocate the stats DMA buffer
because the alloc function pointer (vdev.alloc_consistent) is valid
only in the primary process, not in the secondary process.

Overwriting the alloc function pointer in the secondary process is not
an option, as it will simply make the pointer invalid in the primary
process. Instead, allocate the DMA buffer during probe so that only
the primary process does both allocate and free. This allows the

drops packets larger than the requested size, even though they are
still smaller than MTU.

Cisco VIC does not have such a feature. But, we can accomplish a
similar (not same) effect by reducing the size of posted receive
buffers. Packets larger than the posted size get truncated, and the
receive handler drops them. This is also how the kernel enic driver
enforces the Rx side MTU.

This workaround works only when scatter mode is *not* used. When
scatter is used, there is currently no way to support

Normally, firmware reads various Forward Error Correction parameters
from a Transceiver Module i2c EPROM and uses a couple of IEEE Standards
(802.3bj for 100Gb/s and 802.3by for 25Gb/s) to interpret those
parameters and come up with supported and default FEC settings.
Firmware then sends these FEC parameters to the Host Driver which gives
the Host Administrator an opportunity to change them if necessary in
order to establish a Link with a Switch which may have made a
