[PATCH 1/2] ethdev: add IPsec event subtype range for PMD specific code

[Nithin Dabilpuram]

Add IPsec event subtype range for PMD specific code in order
to accommodate wide range of errors that PMD supports.
These IPsec event subtypes are used when an error doesn't
match the spec defined subtypes between RTE_ETH_EVENT_IPSEC_UNKNOWN
and RTE_ETH_EVENT_IPSEC_MAX. Adding this as -ve error range
to avoid ABI breakage.
