Hi All,
It seems that on FreeBSD, nic_uio currently only binds the devices matched in
rte_pci_dev_ids.h. On Linux, it's possible to bind any listed device with
igb_uio or vfio.
The pci device ids supported by cxgbe PMD, maintained in a table, are not part
of rte_pci_dev_ids.h. Hence, Chelsio
updates
cxgbe documentation to reflect the FreeBSD support for CXGBE PMD.

Adds cxgbe poll mode driver for DPDK under lib/librte_pmd_cxgbe directory. This
patch:
1. Adds the Makefile to compile cxgbe pmd.
2. Registers and initializes the cxgbe pmd driver.

Yes, we will do
Add a sanity check for number of tx descriptors requested during tx
queue setup. Return -EINVAL if the number requested does not meet
the tx descriptor requirements of the device.

Patch 2 replaces spinning for a lock with a better trylock in
tx alarm callback.

is to relax this enforcing in CXGBE PMD. A minimum of 128
descriptors seems to be a good number with the least impact on the
performance.

CXGBE PMD depends on an alarm to periodically transmit any pending
coalesced packets and hence spins for a lock for each tx queue in the
alarm callback.
A better solution is to try to get a lock whenever possible, instead
of spinning for it.

Hi,
We are working towards adding h/w based filtering support in cxgbe PMD.
Chelsio T5 supports carrying out filtering in hardware which supports 3
actions to carry out on a packet which hit a filter viz.
1. Action Pass - Packets hitting a filter rule can be directed to a
particular RXQ.
2.
This series of patches improve forwarding performance for Chelsio T5 40GbE
cards and add Jumbo Frame support for cxgbe pmd. Also update documentation
and release notes.

Add a non-coalesce path. Skip coalescing for Jumbo Frames, and send the
packet through non-coalesced path if there are enough credits. Also,
free these non-coalesced packets while reclaiming credits.

Ensure jumbo mode is enabled and that the mbuf data room size can
accommodate jumbo size. If the mbuf data room size can't accommodate
jumbo size, chain mbufs to jumbo size.
