0f3ff2445d net/cxgbe: announce Rx scatter offload
Scatter Rx is already supported by CXGBE PMD. So, add the missing
DEV_RX_OFFLOAD_SCATTER flag to the list of supported Rx offload
features.

Also, move the macros for supported list of offload features to
header file.

9eb2c9a480 net/cxgbe: implement flow create operation
Define filter work request API used to construct filter operations
to be communicated with firmware. These requests are sent via
control queue and completions come asynchronously in firmware event
queue.

Implement flow create operation to create filters in LE-TCAM
(maskfull) region at specified index.

f5b3c7b293 net/cxgbevf: fix inter-VM traffic when physical link down
Add force_link_up devargs to always force link as up for VFs.
This enables VFs on the same NIC to send traffic to each other
even when physical link is down.

Also add RTE_PMD_REGISTER_PARAM_STRING to export all supported
devargs.

ca0481dade cxgbe: fix minimum descriptors requirement
Most dpdk examples and apps seem to initialize with a minimum of 128 rx
descriptors and 512 tx descriptors for queue setup.  However, CXGBE PMD
enforces a minimum of 1024 descriptors.  This causes the dpdk stack
to return -EINVAL because the apps do not request the minimum required.

The fix 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.

Fixes: 946c9ed95616 ("cxgbe: get descriptor limits")
