2019-10-24net: aquantia: add support for PIN funcsDmitry Bezrukov
Depending on FW configuration we can manage from 0 to 3 PINs for periodic output and from 0 to 1 ext ts PIN for getting TS for external event. Ext TS PIN functionality is implemented via periodic timestamps polling directly from PHY, because right now there is now way to receive the PIN trigger interrupt from phy. The polling interval is 15 milliseconds.

2018-11-14net: aquantia: add support of rx-vlan-filter offloadDmitry Bogdanov

L2 EtherType filters allows to filter packet by EtherType field or both EtherType and User Priority (PCP) field of 802.1Q. UserPriority (vlan) parameter must be accompanied by mask 0x1FFF. That is to distinguish VLAN filter from L2 Ethertype filter with UserPriority since both User Priority and VLAN ID are passed in the same 'vlan' parameter. Example: To add a filter that directs IP4 packess of priority 3 to queue 3: ethtool -N <ethX> flow-type ether proto 0x800 vlan 0x600 m 0x1FFF \ action 3 loc 16 Signed-off-by: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com> Signed-off-by: Igor Russkikh <igor.russkikh@aquantia.com> Signed-off-by: David S.

That is to distinguish VLAN filter from L2 Ethertype filter with UserPriority since both User Priority and VLAN ID are passed in the same 'vlan' parameter. Flow type may be any as it is not matched for VLAN filter. Due to fixed order of the rules in the NIC, the location 0-15 are reserved for vlan filters.

Both IPv4 and IPv6 are supported. The supported actions are the drop and the queue assignment. Due to fixed order of the rules in the NIC, the location 32-39 are reserved for L3/L4 5-tuple filters.

Setting up macvlan/macvtap networks over atlantic NIC results in no traffic over these networks because ndo_set_rx_mode did not listed UC MACs as registered in unicast filter. Here we fix that taking into account maximum number of UC filters supported by hardware. If more than MAX addresses were registered, we just enable promisc and/or allmulti to pass the traffic in.
