net: mvneta: rely on MVNETA_MAX_RX_BUF_SIZE for pkt split in mvneta_swbm_rx_frame() (6eb8b7fb) · Commits · 戴 / test

In order to easily change the rx buffer size, rely on MVNETA_MAX_RX_BUF_SIZE instead of PAGE_SIZE in mvneta_swbm_rx_frame routine for rx buffer split. Currently this is not an issue since we set MVNETA_MAX_RX_BUF_SIZE to PAGE_SIZE - MVNETA_SKB_PAD but it is a good to have to configure a different rx buffer size. Signed-off-by:
