dpdk: show hardware may display the wrong information for rss active
Some dpdk driver does not support rte_eth_dev_rss_hash_conf_get. When that
happens, we display whatever that was in the stack variable for rss_hf which
is confusing.
The fix is to clear rss_hf prior to the call.
Before the fix
--------------
DBGvpp# sh hard
Name Idx Link Hardware
format_dpdk_device:599: rte_eth_dev_rss_hash_conf_get returned -95
GigabitEthernet13/0/0 2 up GigabitEthernet13/0/0
Link speed: 10 Gbps
Ethernet address 00:0c:29:c4:8c:eb
VMware VMXNET3
...
rss avail: ipv4 ipv4-tcp ipv6 ipv6-tcp
rss active: ipv4 ipv4-frag ipv4-tcp ipv4-udp ipv4-other
After the fix
-------------
