[dpdk-dev] [PATCH v3] net/ice: add 1PPS support for E810

The E810 supports four single-ended GPIO signals (SDP[20:23]). The 1PPS signal outputs via SDP[20:23], which is measured by an oscilloscope. This feature can be turned by a devargs which can select GPIO pin index flexibly. Pin index 0 means SDP20, pin index 1 means SDP21 and so on. The example for
