2019-02-06liquidio: Implement ndo_get_port_parent_id()Florian Fainelli1-18/+7
Liquidio only supports SWITCHDEV_ATTR_ID_PORT_PARENT_ID, which makes it a great candidate to be converted to use the ndo_get_port_parent_id() NDO instead of implementing switchdev_port_attr_get().

2018-11-30liquidio: read sc->iq_no before release scPan Bian1-1/+3
The function lio_vf_rep_packet_sent_callback releases the occupation of sc via octeon_free_soft_command. sc should not be used after that. Unfortunately, sc->iq_no is read. To fix this, the patch stores sc->iq_no into a local variable before releasing sc and then uses the local variable instead of sc->iq_no.

2018-09-18net: cavium: fix return type of ndo_start_xmit functionYueHaibing1-2/+3
The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type, so make sure the implementation in this driver has returns 'netdev_tx_t' value, and change the function return type to netdev_tx_t.

2018-08-29liquidio: remove obsolete functions and data structuresFelix Manlunas1-1/+4
1. Remove unused functions and data structures. 2. Change the sending of the remaining soft commands to synchronous. Signed-off-by: Weilin Chang <weilin.chang@cavium.com> Signed-off-by: Felix Manlunas <felix.manlunas@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-08-29liquidio: make soft command calls synchronousFelix Manlunas1-30/+12
1. Add wait_for_sc_completion_timeout() for waiting the response and handling common response errors 2. Send sc's synchronously: remove unused callback function, and context structure; use wait_for_sc_completion_timeout() to wait its response.

2018-04-24liquidio: Swap VF representor Tx and Rx statisticsSrinivas Jampala1-7/+8
Swap VF representor tx and rx interface statistics since it is a virtual switchdev port and tx for VM should be rx for VF representor and vice-versa.

2017-11-02liquidio: synchronize VF representor names with NIC firmwareVijaya Mohan Guvva1-0/+68
LiquidIO firmware supports a vswitch that needs to know the names of the VF representors in the host to maintain compatibility for direct programming using external Openflow agents. So, for each VF representor, send its name to the firmware when it gets registered and when its name changes.

2017-11-01liquidio: Configure switchdev with devlinkVijaya Mohan Guvva1-0/+6
Enable and disable switchdev on SRIOV capable LiquidIO NIC with devlink. Create representor netdev for each SRIOV VF function on SRIOV enable and and do the cleanup on SRIOV disable.

2017-11-01liquidio: switchdev support for LiquidIO NICVijaya Mohan Guvva1-0/+621
Enable switchdev for SRIOV capable LiquidIO NIC. It registers a representor netdev (with switchdev_ops) for each SRIOV VF created. It also has changes to send representor interface configurations like admin state and MTU to LiquidIO firmware and to retrieve HW counted VF stats for VF representor.
