[PATCH v4] [PATCH 1/2] net/tap: fix buffer overflow for ptypes list

[Sivaramakrishnan Venkat]

Incorrect ptypes list causes buffer overflow for Address Sanitizer
run. The last element in the ptypes lists to be "RTE_PTYPE_UNKNOWN"
for rte_eth_dev_get_supported_ptypes().
In rte_eth_dev_get_supported_ptypes(),the loop iterates until it
finds "RTE_PTYPE_UNKNOWN" to detect last element of the ptypes array.
Fix the ptypes list for drivers.

Fixes: 0849ac3b6122 ("net/tap: add packet type management")
Fixes: a7bdc3bd4244 ("net/dpaa: support packet type parsing")
Fixes: 4ccc8d770d3b ("net/mvneta: add PMD skeleton")
Fixes: f3f0d77db6b0 ("net/mrvl: support packet type parsing")
Fixes: 78a38edf66de ("ethdev: query supported packet types")
Fixes: 659b494d3d88 ("net/pfe: add packet types and basic statistics")
Fixes: 398a1be14168 ("net/thunderx: remove generic passX references")
