The switch is reached through four register functions and the SFR_DATA registers, so a flat register file behind them is enough to run the table code on the host. A few addresses are live: writing TBL_CTRL with EXECUTE performs the VLAN or L2 operation at once and clears the bit, STAT_GET fetches a counter, L2_TBL_FLUSH_CTRL drops entries. Nothing ever reports busy, so a polling loop runs once and the tests say nothing about what happens when hardware stalls; that question was settled elsewhere. The header states the VLAN and L2 entry layouts on its own, so a test can hold what rtl837x_port.c writes against a second reading of the same bits rather than against itself. The first suite does that for the VLAN entry, the PVID register two ports share, the static multicast and management entries, the per-port flush and the trunk registers. Two stub headers stand in for the ones a firmware build generates, so the harness needs no SDCC build first.
