eventdev: fix telemetry Rx adapters stats reset
Checks
Commit Message
Caught by covscan:
1. dpdk-21.11/lib/eventdev/rte_event_eth_rx_adapter.c:3279:
logical_vs_bitwise: "~(*__ctype_b_loc()[(int)*params] & 2048 /*
(unsigned short)_ISdigit */)" is always 1/true regardless of the values
of its operand. This occurs as the logical second operand of "||".
2. dpdk-21.11/lib/eventdev/rte_event_eth_rx_adapter.c:3279: remediation:
Did you intend to use "!" rather than "~"?
While isdigit return value should be compared as an int to 0,
prefer ! since all of this file uses this convention.
Fixes: 814d01709328 ("eventdev/eth_rx: support telemetry")
