bmc_tx_filter_main and bmc_update_cache_main are sched_cls (TC) programs but returned XDP_PASS on their early-out paths. XDP_PASS == 2 == TC_ACT_SHOT, so a short frame (ip + 1 > data_end) and the !stats paths were dropped instead of passed. Use TC_ACT_OK, matching every other return in these functions.
