2020-11-23net: don't include ethtool.h from netdevice.hJakub Kicinski1-0/+2
linux/netdevice.h is included in very many places, touching any of its dependecies causes large incremental builds. Drop the linux/ethtool.h include, linux/netdevice.h just needs a forward declaration of struct ethtool_ops. Fix all the places which made use of this implicit include.

2020-10-06net: atlantic: implement media detect feature via phy tunablesIgor Russkikh1-0/+2
Mediadetect is another name for the EDPD (energy detect power down). This feature allows device to save extra power when no link is available. PHY goes into the extreme power saving mode and only periodically wakes up and checks for the link. AQC devices has fixed check period of 6 seconds The feature may increase linkup time.

PHY downshift allows phy to try renegotiate if link is unstable and can carry higher speed. AQC devices has integrated PHY which is controlled by MAC firmware. Thus, driver defines new ethtool callbacks to implement phy tunables via netdev. Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Igor Russkikh <irusskikh@marvell.com> Signed-off-by: David S.

2020-07-25Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/netDavid S. Miller1-0/+2
The UDP reuseport conflict was a little bit tricky. The net-next code, via bpf-next, extracted the reuseport handling into a helper so that the BPF sk lookup code could invoke it. At the same time, the logic for reuseport handling of unconnected sockets changed via commit efc6b6f6c3113e8b203b9debfb72d81e0f3dcace which changed the logic to carry on the reuseport result into the rest of the lookup loop if we do not return immediately. This requires moving the reuseport_has_conns() logic into the callers. While we are here, get rid of inline directives as they do not belong in foo.c files. The other changes were cases of more straightforward overlapping modifications. Signed-off-by: David S. Miller <davem@davemloft.net>
2020-07-17net: atlantic: disable PTP on AQC111, AQC112Nikita Danilov1-0/+2
This patch disables PTP on AQC111 and AQC112 due to a known HW issue, which can cause datapath issues. Ideally PTP block should have been disabled via PHY provisioning, but unfortunately many units have been shipped with enabled PTP block. Thus, we have to work around this in the driver.

2020-05-22net: atlantic: automatically downgrade the number of queues if necessaryMark Starovoytov1-0/+1
This patch adds support for automatic queue number downgrade. On A2: this is a must have, because only TC0/TC1 support more than 4Q. Other TCs support 4Qs maximum. Thus, on A2 we must downgrade the number of queues per TC to 4, if more than 2 TCs are requested. On A1: this allows using 8TCs even on systems with cpu count >= 8, when we have 8 queues by default. We will just automatically switch to 8TCx4Q mode in this case. Signed-off-by: Mark Starovoytov <mstarovoitov@marvell.com> Signed-off-by: Igor Russkikh <irusskikh@marvell.com> Signed-off-by: David S.

In the first generation of our hardware (A1), a whole traffic class is consumed for PTP handling in FW (FW uses it to send the ptp data and to send back timestamps).

In configuration of vlan over bridge over aquantia device it was found that vlan tagged traffic is dropped on chip.

2018-01-16net: aquantia: Eliminate aq_nic structure abstractionIgor Russkikh1-1/+33
aq_nic_s was hidden in aq_nic_internal.h, that made it difficult to access nic fields and structures from other modules. This change moves aq_nic_s struct into aq_nic.h and thus makes it available to other driver modules, mainly pci module and hw related module.
