net: ena: Add device reload capability through devlink

2025-06-19T01:57:28Z

Adding basic devlink capability support of reloading the driver. This capability is required to support driver init type devlink params (DEVLINK_PARAM_CMODE_DRIVERINIT). Such params require reloading of the driver (destroy/restore sequence). The reloading is done by the devlink framework using the hooks provided by the driver.

net: ena: Add PHC support in the ENA driver

2025-06-19T01:57:28Z

The ENA driver will be extended to support the new PHC feature using ptp_clock interface [1]. this will provide timestamp reference for user space to allow measuring time offset between the PHC and the system clock in order to achieve nanosecond accuracy.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21Z

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

net: ena: Select DIMLIB for ENA_ETHERNET

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 commit 282faf61a053 ("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.
