2019-09-05ice: clean up argumentsJesse Brandeburg
There are a couple of functions that don't need two arguments passed in when the second argument already had access to the pointer pointed to by the first. Remove the unnecessary arguments.

2019-09-05ice: Check root pointer for validityAnirudh Venkataramanan
ice_sched_get_tc_node uses pi->root without checking for NULL. Add a check to prevent NULL pointer dereference. Signed-off-by: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2019-09-05ice: Add ice_get_main_vsi to get PF/main VSIAnirudh Venkataramanan
There are multiple places where we currently use ice_find_vsi_by_type to get the PF (a.k.a. main) VSI. The PF VSI by definition is always the first element in the pf->vsi array (i.e. pf->vsi[0]). So instead add and use a new helper function ice_get_main_vsi, which just returns pf->vsi[0].

2019-09-05ice: Update fields in ice_vsi_set_num_qs when reconfiguringBrett Creeley
Currently when vsi->req_txqs or vsi->req_rxqs are set we don't correctly set the number of vsi->num_q_vectors. Fix this by setting the number of queue vectors based on the max between the vsi->alloc_txqs and vsi->alloc_rxqs.

2019-09-05ixgbe: fix xdp handle calculationsKevin Laatz
Currently, we don't add headroom to the handle in ixgbe_zca_free, ixgbe_alloc_buffer_slow_zc and ixgbe_alloc_buffer_zc. The addition of the headroom to the handle was removed in commit d8c3061e5edd ("ixgbe: modify driver for handling offsets"), which will break things when headroom isvnon-zero. This patch fixes this and uses xsk_umem_adjust_offset to add it appropritely based on the mode being run.

2019-09-05gianfar: use DT more consistently when selecting PHY connection typeArseny Solokha
Historically, gianfar only used phy-connection-type DT property when connected to PHY in the rgmii-id mode. It ignored the property otherwise, relying on the connection type auto-detection carried out by MAC and providing that reconstructed mode to of_phy_connect(). It also did not consider alternative phy-mode property at all. Make the driver properly query DT node for PHY connection type first and use an obtained value if it was specified there. Otherwise, if a particular DT relies on connection type auto-detection, fall back to reconstructing the value from MAC registers, as before.

2019-09-05net: stmmac: Only consider RX error when HW Timestamping is not enabledJose Abreu

2019-09-05ionic: Add the basic NDO callbacks for netdev supportShannon Nelson

2019-09-05ionic: Add notifyq supportShannon Nelson

2019-09-05ionic: Add interrupts and doorbellsShannon Nelson
The ionic interrupt model is based on interrupt control blocks accessed through the PCI BAR. Doorbell registers are used by the driver to signal to the NIC that requests are waiting on the message queues. Interrupts are used by the NIC to signal to the driver that answers are waiting on the completion queues. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-09-05ionic: Add basic lif supportShannon Nelson
