2016-04-26cxgb4: add new routine to get adapter infoHariprasad Shenai

Conflicts were two cases of simple overlapping changes, nothing serious. In the UDP case, we need to add a hlist_add_tail_rcu() to linux/rculist.h, because we've moved UDP socket handling away from using nulls lists. Signed-off-by: David S. Miller <davem@davemloft.net>

2016-04-15cxgb4: Set VPD size so we can read both VPD structuresHariprasad Shenai
Chelsio adapters have two VPD structures stored in the VPD: - offset 0x000: an abbreviated VPD, and - offset 0x400: the complete VPD. After 104daa71b396 ("PCI: Determine actual VPD size on first access"), the PCI core computes the valid VPD size by parsing the VPD starting at offset 0x0. That size only includes the abbreviated VPD structure, so reads of the complete VPD at 0x400 fail. Explicitly set the VPD size with pci_set_vpd_size() so the driver can read both VPD structures.

2016-04-11cxgb4: Stop Rx Queues before freeing it upHariprasad Shenai
Stop all Ethernet RX Queues before freeing up various Ingress/Egress Queues, etc. We were seeing cases of Ingress Queues not getting serviced during the shutdown process leading to Ingress Paths jamming up through the chip and blocking the shutdown effort itself. One such case involved the Firmware sending a "Flush Token" through the ULP-TX -> ULP-RX path for an Ethernet TX Queue being freed in order to make sure there weren't any remaining TX Work Requests in the pipeline. But the return path was stalled by Ingress Data unable to be delivered to the Host because those Ingress Queues were no longer being serviced.

So if we set FBMIN to 64 bytes and the Host Driver supplies 128 bytes of Free List Pointer data, the hardware will issue two 64-byte PCI-E Fetch Requests rather than a single coallesced 128-byte Fetch Request.

2016-02-11cxgb4/iw_cxgb4: TOS supportHariprasad Shenai
This series provides support for iWARP applications to specify a TOS value and have that map to a VLAN Priority for iw_cxgb4 iWARP connections. In iw_cxgb4, when allocating an L2T entry, pass the skb_priority based on the tos value in the cm_id. Also pass the correct tos value during connection setup so the passive side gets the client's desired tos. When sending the FLOWC work request to FW, if the egress device is in a vlan, then use the vlan priority bits as the scheduling class. This allows associating RDMA connections with scheduling classes to provide traffic shaping per flow.
