ice: Avoid setting default Rx VSI twice in switchdev setup
[ Upstream commit 5c07be96d8b3f8447e980f29b967bf2e1d7ac732 ]
As part of switchdev environment setup, uplink VSI is configured as
default for both Tx and Rx. Default Rx VSI is also used by promiscuous
mode. If promisc mode is enabled and an attempt to enter switchdev mode
is made, the setup will fail because Rx VSI is already configured as
default (rule exists).
Reproducer:
devlink dev eswitch set $PF1_PCI mode switchdev
ip l s $PF1 up
ip l s $PF1 promisc on
echo 1 > /sys/class/net/$PF1/device/sriov_numvfs
In switchdev setup, use ice_set_dflt_vsi() instead of plain
ice_cfg_dflt_vsi(), which avoids repeating setting default VSI for Rx if
it's already configured.
Fixes: 50d62022f455 ("ice: default Tx rule instead of to queue")
