ethtool: extend ringparam setting/getting API with rx_buf_len

2021-11-22T12:31:49Z

Add two new parameters kernel_ringparam and extack for .get_ringparam and .set_ringparam to extend more ring params through netlink. Signed-off-by: Hao Chen Signed-off-by: Guangbin Huang Signed-off-by: David S. Miller

ethtool: extend coalesce setting uAPI with CQE mode

2021-08-24T14:38:29Z

In order to support more coalesce parameters through netlink, add two new parameter kernel_coal and extack for .set_coalesce and .get_coalesce, then some extra info can return to user with the netlink API. Signed-off-by: Yufeng Mo Signed-off-by: Huazhong Tan Signed-off-by: Jakub Kicinski

s390/qeth: remove OSN support

2021-07-20T13:17:06Z

Commit fb64de1bc36c ("s390/qeth: phase out OSN support") spelled out why the OSN support in qeth is in a bad shape, and put any remaining interested parties on notice to speak up before it gets ripped out. It's 2021 now, so make true on that promise and remove all the OSN-specific parts from qeth. This also means that we no longer need to export various parts of the cmd & data path internals to the L2 driver. Signed-off-by: Julian Wiedmann Reviewed-by: Alexandra Winter Signed-off-by: David S.

s390/qeth: use ethtool_sprintf()

2021-06-11T19:49:15Z

Use a recently introduced helper to fill our ethtool stats strings. Signed-off-by: Julian Wiedmann Signed-off-by: David S. Miller

s390/qeth: count TX completion interrupts

2021-06-11T19:49:15Z

While the qdio layer already tracks the number of HW interrupts for a device, there's value in understanding how many of them have been raised due to our TX completion logic. Signed-off-by: Julian Wiedmann Signed-off-by: David S. Miller

s390/qeth: improve selection of ethtool link modes

2020-11-19T01:34:19Z

The link mode is a combination of port speed and port mode. But we currently only consider the speed, and then typically select the corresponding TP-based link mode. For 1G and 10G Fibre links this means we display the wrong link modes. Move the SPEED_* switch statements inside the PORT_* cases, and only consider valid combinations where we can select the corresponding link mode. Add the relevant link modes (1000baseX, 10000baseSR and 1000baseLR) that were introduced back with commit 5711a9822144 ("net: ethtool: add support for 1000BaseX and missing 10G link modes"). To differentiate between 10000baseSR and 10000baseLR, use the detailed media_type information that QUERY OAT provides. Signed-off-by: Julian Wiedmann Signed-off-by: Jakub Kicinski

s390/qeth: clean up default cases for ethtool link mode

2020-11-19T01:34:19Z

Remove the default case for PORT_* and SPEED_* in our ethtool code. The only time these could be hit is if qeth_init_link_info() was unable to determine the port type from an OSA adapter's link_type. We already throw a message in this case, so reduce the noise and don't report bad data (ie. it's much more likely that any future link_type will represent a PORT_FIBRE link ...).

s390/qeth: set static link info during initialization

2020-11-19T01:34:19Z

Hard-code the minimal link info at initialization time, after we obtained the link_type. qeth_get_link_ksettings() can still override this with more accurate data from QUERY CARD INFO later on. Don't set arbitrary defaults for unknown OSA link types, they certainly won't match any future type. Signed-off-by: Julian Wiedmann Signed-off-by: Jakub Kicinski

s390/qeth: improve QUERY CARD INFO processing

2020-11-19T01:34:19Z

Move all the HW reply data parsing into qeth_query_card_info_cb(), and use common ethtool enums for transporting the information back to the caller. Also only look at the .port_speed field when we couldn't determine the speed from the .card_type field, and introduce some 'default' cases for SPEED_UNKNOWN, PORT_OTHER and DUPLEX_UNKNOWN.

s390/qeth: tolerate error when querying card info

2020-11-19T01:34:18Z

By the time that our .get_link_ksettings() code issues a QUERY CARD INFO cmd to get link-related information, we already set up a good amount of static link data. Return this data when the cmd fails, same as when the cmd is not supported. Signed-off-by: Julian Wiedmann Signed-off-by: Jakub Kicinski
