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().

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.

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.

1. Remove unused functions and data structures.
2. Change the sending of the remaining soft commands to synchronous.

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.

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.

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.

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.

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.
