* cxgb4: Setup FW queues before registering netdevArjun Vynipadath2018-03-261-3/+8
| | | | | | | | | | | | | | When NetworkManager is enabled, there are chances that interface up is called even before probe completes. This means we have not yet allocated the FW sge queues, hence rest of ingress queue allocation wont be proper. Fix this by calling setup_fw_sge_queues() before register_netdev().

For the mac80211 stuff, these were fortunately just parallel adds. Trivially resolved. In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the function phy_disable_interrupts() earlier in the file, whilst in 'net-next' the phy_error() call from this function was removed. In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the 'rt_table_id' member of rtable collided with a bug fix in 'net' that added a new struct member "rt_mtu_locked" which needs to be copied over here. The mlxsw driver conflict consisted of net-next separating the span code and definitions into separate files, whilst a 'net' bug fix made some changes to that moved code. The mlx5 infiniband conflict resolution was quite non-trivial, the RDMA tree's merge commit was used as a guide here, and here are their notes: ==================== Due to bug fixes found by the syzkaller bot and taken into the for-rc branch after development for the 4.17 merge window had already started being taken into the for-next branch, there were fairly non-trivial merge issues that would need to be resolved between the for-rc branch and the for-next branch. This merge resolves those conflicts and provides a unified base upon which ongoing development for 4.17 can be based. Conflicts: drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524 (IB/mlx5: Fix cleanup order on unload) added to for-rc and commit b5ca15ad7e61 (IB/mlx5: Add proper representors support) add as part of the devel cycle both needed to modify the init/de-init functions used by mlx5. To support the new representors, the new functions added by the cleanup patch needed to be made non-static, and the init/de-init list added by the representors patch needed to be modified to match the init/de-init list changes made by the cleanup patch. Updates: drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function prototypes added by representors patch to reflect new function names as changed by cleanup patch drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init stage list to match new order from cleanup patch ==================== Signed-off-by: David S.

| * PCI/cxgb4: Extend T3 PCI quirk to T4+ devicesCasey Leedom2018-02-161-10/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've run into a problem where our device is attached to a Virtual Machine and the use of the new pci_set_vpd_size() API doesn't help. The VM kernel has been informed that the accesses are okay, but all of the actual VPD Capability Accesses are trapped down into the KVM Hypervisor where it goes ahead and imposes the silent denials. The right idea is to follow the kernel.org commit 1c7de2b4ff88 ("PCI: Enable access to non-standard VPD for Chelsio devices (cxgb3)") which Alexey Kardashevskiy authored to establish a PCI Quirk for our T3-based adapters. This commit extends that PCI Quirk to cover Chelsio T4 devices and later. The advantage of this approach is that the VPD Size gets set early in the Base OS/Hypervisor Boot and doesn't require that the cxgb4 driver even be available in the Base OS/Hypervisor. Thus PF4 can be exported to a Virtual Machine and everything should work.
