This patch adds miscellaneous files for the Altera Ethernet Driver, including ethtool support. Signed-off-by: Vince Bridgers <vbridgers2013@xxxxxxxxx> --- V2: - Break up driver files for initial submission by logical function. - Change bus type in ethtool from "AVALON" to "platform" --- drivers/net/ethernet/altera/altera_tse_ethtool.c | 226 ++++++++++++++++++++++ drivers/net/ethernet/altera/altera_utils.c | 44 +++++ drivers/net/ethernet/altera/altera_utils.h | 27 +++ 3 files changed, 297 insertions(+) create mode 100644 drivers/net/ethernet/altera/altera_tse_ethtool.c create mode 100644 drivers/net/ethernet/altera/altera_utils.c create mode 100644 drivers/net/ethernet/altera/altera_utils.h diff --git a/drivers/net/ethernet/altera/altera_tse_ethtool.c b/drivers/net/ethernet/altera/altera_tse_ethtool.c new file mode 100644 index 0000000..02821b6 --- /dev/null +++ b/drivers/net/ethernet/altera/altera_tse_ethtool.c @@ -0,0 +1,226 @@ +/* Ethtool support for Altera Triple-Speed Ethernet MAC driver + * Copyright (C) 2008-2014 Altera Corporation.
