This patch introduces run-time board detection through DMI and MAC-PHY configuration function used by quark_default_data() during initialization. It fills up the phy_addr for Galileo and Galileo Gen2 boards to indicate that the Ethernet MAC controller is or is not connected to any PHY. The implementation takes into consideration for future expansion in Quark series boards that may have different PHY address that is linked to its MAC controllers. This piece of work is derived from Bryan O'Donoghue's initial work for Quark X1000 enabling. Signed-off-by:

The Intel Quark SoC X1000 provides two 10/100 Mbps Ethernet MAC controllers which may or may not be connected to PHY on board. This MAC controller only supports RMII PHY. This patch add Quark PCI ID as well as Quark default platform data info to this driver. Signed-off-by:

This patch fix is to use default firmware configuration files present in the adapter incase if not available in standard /lib/firmware/* dir. Additional cleanup is done to reuse flash related defines from cxgb4 header file. Please apply over net-next since it depends on previous commit. Signed-off-by:

Amir Vadai says: ==================== Mellanox ethernet driver updates Jan-27-2015 This patchset introduces some bug fixes, code cleanups and support in a new firmware event called recoverable error events. Patches were applied and tested against commit b8665c6c ("net: dsa/mv88e6352: make mv88e6352_wait generic") Changes from V0: - Patch 6/11 ("net/mlx4_core: Fix struct mlx4_vhcr_cmd to make implicit padding explicit"): - Removed __packed - Rephrased commit message - Added a new patch by Majd ("net/mlx4_core: Update the HCA core clock frequency after INIT_PORT") ==================== Signed-off-by:

The firmware might change the hca core clock frequency after the driver issues the INIT_PORT command. Therefore we need to query the new value again and save in to the cached dev caps. Fixes: ddd8a6c1 ('net/mlx4_core: Read HCA frequency and map internal clock') Signed-off-by:

Fix a memory corruption at mlx4_MAD_IFC_wrapper.

When cmd->autoneg == AUTONEG_ENABLE set according to ethtool->advertise otherwise, set according to ethtool->speed. Usage: - ethtool -s eth<x> speed 56000 autoneg off - ethtool -s eth<x> advertise 0x800000 autoneg on While we're here: - Move proto_admin masking outcome check to be adjacent to the operation. - Move en_warn("port reset..") print to "port reset" block.

Struct mlx4_vhcr was implicitly padded by the gcc compiler on 64-bit architectures. This commit makes that padding explicit, to prevent issues with changing compilers and with incompatibilities between 32-bit architecture implicit padding and 64-bit architecture implicit padding. This structure is used in virtualization for communication between the Host and its Guests. The explicit padding allows 64-bit Hosts (old and new) to continue to interoperate with 64-bit Guests (old and new). However, without this fix, 64-bit Hosts could not interoperate with 32-bit Guests (since these did not insert the padding dword). With this fix, 32-bit Guests will be able to interoperate with 64-bit Hosts (since the structure offsets will be identical on both). Reported-by:

The driver incorrectly assigned an out-mailbox to this command, and used an opcode modifier = 0, which is a reserved value (it should use opcode modifier = 1). Signed-off-by:

The firmware spec states that the timeout for all commands should be 60 seconds. In the past, the spec indicated that there were several classes of timeout (short, medium, and long). The driver has these different timeout classes. We leave the class differentiation in the driver as-is (to protect against any future spec changes), but set the timeout for all classes to be 60 seconds. In addition, we fix a few commands which had hard-coded numeric timeouts specified. Signed-off-by:

The reserved lKey is different for each VF. A base lkey value is returned in QUERY_DEV_CAP at offset 0x98. The reserved L_key value for a VF is: VF_lkey = base_lkey + (VF_number << 8). This VF L_key value should be returned in QUERY_FUNC_CAP (opcode-modifier = 0) at offset 0x48. To indicate that the lkey value at offset 0x48 is valid, the Hypervisor sets a flag bit in dword 0x0, offset 27 in the QUERY_FUNC_CAP wrapper function. When the VF calls QUERY_FUNC_CAP, it should check if this flag bit is set. If it is set, the VF should take the reserved lkey value at offset 0x48. If the bit is not set, the VF should not use a reserved lkey (i.e., should set its reserved lkey value to 0). Signed-off-by: -

Previous commit is based on a wrong assumption, fdb messages are always sent into the netns where the interface stands (see vxlan_fdb_notify()). These fdb messages doesn't embed the rtnl attribute IFLA_LINK_NETNSID, thus we need to add it (useful to interpret NDA_IFINDEX or NDA_DST for example). Note also that vxlan_nlmsg_size() was not updated. Fixes: 193523bf ("vxlan: advertise netns of vxlan dev in fdb msg") Signed-off-by:

Jonathan Toppins says: ==================== bonding: various 802.3ad fixes This patch series is a forward porting of patches we (Cumulus) are shipping in our 3.2 series kernels. These fixes attempt to make 802.3ad bonding mode more predictable in certian state machine transtions in addition to fixing 802.3ad bond carrier determination when bonding min_links option is changed. Specific notes are contained within each patch. For this patch series there are no userspace facing changes, a diff between the modinfo output showed no difference. However, there are behavioral facing changes, primarily in the bond carrier state. Please make sure to review carefully. v2: * fixed some style issues * dropped a portion of patch 1 in favor of more testing on my side ==================== Signed-off-by:

This patch attempts to fix the following problems when an actor or partner's aggregator is not active: 1. a slave's lacp port state is marked as AD_STATE_SYNCHRONIZATION even if it is attached to an inactive aggregator. LACP advertises this state to the partner, making the partner think he can move into COLLECTING_DISTRIBUTING state even though this link will not pass traffic on the local side 2. a slave goes into COLLECTING_DISTRIBUTING state without checking if the aggregator is actually active 3. when in COLLECTING_DISTRIBUTING state, the partner parameters may change, e.g. the partner_oper_port_state.SYNCHRONIZATION. The local mux machine is not reacting to the change and continue to keep the slave and bond up 4. When bond slave leaves an inactive aggregator and joins an active aggregator, the actor oper port state need to update to SYNC state. v2: * fix style issues in bond_3ad.c Cc: Andy Gospodarek <gospo@cumulusnetworks.com> Reviewed-by:Wilson Kok <wkok@cumulusnetworks.com> Signed-off-by:

Mode 802.3ad, fix incorrect bond slave active state when slave is not in active aggregator. During bond_open(), the bonding driver always sets the slave active flag to true if the bond is not in active-backup, alb, or tlb modes. Bonding should let the aggregator selection logic set the active flag when in 802.3ad mode. Cc: Andy Gospodarek <gospo@cumulusnetworks.com> Reviewed-by:

David L Stevens authored
If a remote machine crashes while there are pending transmit buffers, the sunvnet driver reallocates the ring descriptors giving us enries that have state VIO_DESC_FREE but also an allocated skb. This results in a BUG_ON() call when the remote reboots and we reach that point in the ring. This patch: 1) clears pending tx packets in the ring on port reset 2) changes a BUG_ON() to a pr_warn() when a remote host has given us an invalid descriptor state 3) collapses multiple active buffer frees in a ring to a single message per ring and adds the device name and remote MAC address This fixes the particular problem of not cleaning up pending buffers on a reset, but also prevents us from crashing if the remote handles descriptors out of order or sets an unexpected state for a descriptor.
