If CONFIG_ENA_ETHERNET=y and CONFIG_DIMLIB=n, below erros can be found: drivers/net/ethernet/amazon/ena/ena_netdev.o: In function `ena_dim_work': ena_netdev.c:(.text+0x21cc): undefined reference to `net_dim_get_rx_moderation' ena_netdev.c:(.text+0x21cc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `net_dim_get_rx_moderation' drivers/net/ethernet/amazon/ena/ena_netdev.o: In function `ena_io_poll': ena_netdev.c:(.text+0x7bd4): undefined reference to `net_dim' ena_netdev.c:(.text+0x7bd4): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `net_dim' After commit282faf61a0("net: ena: switch to dim algorithm for rx adaptive interrupt moderation"), it introduces dim algorithm, which configured by CONFIG_DIMLIB. So, this patch is to select DIMLIB for ENA_ETHERNET.

If you have a network (Ethernet) device belonging to this class, say Y.

Note that the answer to this question doesn't directly affect the

kernel: saying N will just cause the configurator to skip all

the questions about Amazon devices. If you say Y, you will be asked
