[dpdk-dev,v2] testpmd check return value of rte_eth_dev_vlan_filter()

  This patch modifies testpmd behavior when setting:
rx_vlan add all vf_port (enabling all vlanids
to be passed thru rx filter on VF).
Rx_vlan_all_filter_set() function,
checks if the next vlanid can be enabled by the driver.
Number of vlanids is limited by the NIC and thus the NIC
do not allow to enable more vlanids than it can allocate
in VFTA table.

v2 - fix formatting errors

Hi Michael,
I am sorry I am writing almost a month after you reply
But I had another issues required a 100% attention.

As I see in the function:
rte_eth_dev_vlan_filter(uint8_t port_id, uint16_t vlan_id, int on);
arguments like port_id and vlan_id are checked.  Also if vlan-filtering
is enabled is checked. Each error is printed so the user is informed that
something went wrong and where to look for it.
I don't know what else could be checked here?

v3 changes:
- add seperate patch with testpmd_funcs.rst changes

v2 changes:
- fix formatting errors

This patchset modifies testpmd behavior when setting:
rx_vlan add all vf_port (enabling all vlanids
to be passed thru rx filter on VF).
Rx_vlan_all_filter_set() function,
checks if the next vlanid can be enabled by the driver.
Number of vlanids is limited by the NIC and thus the NIC
do not allow to enable more vlanids than it can allocate
in VFTA table.
tespmd_funcs.rst file is modified to provide a brief description
why enabling all vlan ids may not be possible.

Michal Jastrzebski (2):
  doc: add information about limited number of vlan_ids
  testpmd: check return value of rte_eth_dev_vlan_filter()
