2016-07-04net: ethernet: bcmgenet: use phy_ethtool_{get|set}_link_ksettingsPhilippe Reynes1-26/+2
There are two generics functions phy_ethtool_{get|set}_link_ksettings, so we can use them instead of defining the same code in the driver. Signed-off-by: Philippe Reynes <tremyfr@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The private structure contain a pointer to phydev, but the structure net_device already contain such pointer. So we can remove the pointer phy in the private structure, and update the driver to use the one contained in struct net_device.

2016-07-02bnxt_en: Do function reset on the 1st PF open only.Michael Chan2-6/+17
Calling the firmware to do function reset on the PF will kill all the VFs. To prevent that, we call function reset on the 1st PF open before any VF can be activated. On subsequent PF opens (with possibly some active VFs), a bit has been set and we'll skip the function reset. VF driver will always do function reset on every open. If there is an AER event, we will always do function reset. Signed-off-by: Michael Chan <michael.chan@broadocm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-06-17bnxt: Move GENEVE support from hard-coded port to using port notifierAlexander Duyck2-6/+33
The port number for GENEVE is hard coded into the bnxt driver. This is the kind of thing we want to avoid going forward.

2016-06-14bnxt_en: Add function for VF driver to query default VLAN.Michael Chan2-2/+48
The PF can setup a default VLAN for a VF. The default VLAN tag is automatically inserted and stripped without the knowledge of the stack running on the VF. The VF driver needs to know that default VLAN is enabled as VLAN acceleration on the RX side is no longer supported. Call netdev_update_features() to fix up the VLAN features as necessary. Also, VLAN strip mode must be enabled to strip out the default VLAN tag. Only allow VF default VLAN to be set if the firmware spec is >= 1.2.1.

2016-06-05bnx2x: allow adding VLANs while interface is downMichal Schmidt1-89/+62
Since implementing VLAN filtering in commit 05cc5a39ddb74 ("bnx2x: add vlan filtering offload") bnx2x refuses to add a VLAN while the interface is down: # ip link add link enp3s0f0 enp3s0f0_10 type vlan id 10 RTNETLINK answers: Bad address and in dmesg (with bnx2x.debug=0x20): bnx2x: [bnx2x_vlan_rx_add_vid:12941(enp3s0f0)]Ignoring VLAN configuration the interface is down Other drivers have no problem with this. Fix this peculiar behavior in the following way: - Accept requests to add/kill VID regardless of the device state. Maintain the requested list of VIDs in the bp->vlan_reg list. - If the device is up, try to configure the VID list into the hardware. If we run out of VLAN credits or encounter a failure configuring an entry, fall back to accepting all VLANs. If we successfully configure all entries from the list, turn the fallback off. - Use the same code for reconfiguring VLANs during NIC load.

2016-05-20net: define gso types for IPx over IPv4 and IPv6Tom Herbert2-6/+4
This patch defines two new GSO definitions SKB_GSO_IPXIP4 and SKB_GSO_IPXIP6 along with corresponding NETIF_F_GSO_IPXIP4 and NETIF_F_GSO_IPXIP6. These are used to described IP in IP tunnel and what the outer protocol is. The inner protocol can be deduced from other GSO types (e.g. SKB_GSO_TCPV4 and SKB_GSO_TCPV6). The GSO types of SKB_GSO_IPIP and SKB_GSO_SIT are removed (these are both instances of SKB_GSO_IPXIP4). SKB_GSO_IPXIP6 will be used when support for GSO with IP encapsulation over IPv6 is added.
