dpdk: fix variable type in pattern parsing
In current pattern parsing function in DPDK, some of the variables of packet length are defined as uint8_t, which are too small for some large-size packets, such as srv6. Change the type to uint16_t.

Subject: [PATCH v1] net: fix pkt length type for raw pattern
|
||||
|
||||
In current pattern parsing function for raw pattern, the packet length
|
||||
variable is defined as uint8_t, which is too small for a large packet,
|
||||
such as srv6. Change the type to uint16_t.
