Subject: [PATCH ethtool 1/3] Update FAM syntax to conform to std C.

Found via gcc -fanalyzer. When using the non-standard FAM syntax:

    uint32_t req_mask[0];

gcc-13 with the -fanalyzer flag generates an internal compiler error.
Updating the syntax to use the standard C syntax:

    uint32_t req_mask[];

works around the gcc bug.
