[][HIGH][kernel][common][eth][Fix the GDM TX/RX packet statistics error issue]

[Description]
Fix the GDM TX/RX packet statistics error issue.

The GDM TX/RX hardware counter is designed to clear data
after reading, so the statistical values are reset to
zero once they are read.

We have found that both the GDM TX/RX packet statistics
function and the GDM monitoring function access the
hardware counter, which leads to data contention and
results in incorrect statistical values. There must be
only one single place to read the hardware counter.

Without this patch, the packet count statistics for GDM
TX/RX in the Ethernet driver will be incorrect, and the
packet count statistics seen using the ifconfig command
will also be incorrect.
