25f5b7c78c net/ice/base: fix symmetric hash configure
When a new hash profile is created, we need to reset all related
GLQF_HSYMM registers, otherwise unexpected hash behaviour may happen
on packet that hits that profile.

The patch fixes the issue that we only do reset when symmetric hash
is required, but actually for non symmetric hash we also need this,
since GLQF_HSYMM might be polluted by previous configuration.

fe33a6a65f net/ice/base: fix ptype mapping pollution from GTP flow

which is unexpected. For example, a RSS flow for inner IP / UDP on
regular tunnel packet's behaviour will be changed by a following GTP RSS
rule where inner IP is the only inputset, since all tunnel ptypes have
been shifted from the first profile to the second one.

e8b081e20d net/pcap: fix argument checks
Previously rx/tx_queues were passed into eth_from_pcaps_common()
as ptrs and were checked for being NULL.

In commit da6ba28f0540 ("net/pcap: use a struct to pass user options")
that changed to pass in a ptr to a pmd_devargs_all which contains
the rx/tx_queues.

The parameter checking was not updated as part of that commit and
coverity caught that there was still a check if rx/tx_queues were
NULL, apparently after they had been dereferenced.

In fact as they are a members of the devargs_all struct, they will
not be NULL so remove those checks.

1231        struct pmd_devargs *rx_queues = &devargs_all->rx_queues;
1232        struct pmd_devargs *tx_queues = &devargs_all->tx_queues;
1233        const unsigned int nb_rx_queues = rx_queues->num_of_queue;
    deref_ptr: Directly dereferencing pointer tx_queues.
1234        const unsigned int nb_tx_queues = tx_queues->num_of_queue;
1235        unsigned int i;

    the check.

1241                return -1;
