QPs that were configured with ack timeout value lower than 1 msec will not implement re-transmission timeout. This means that if a packet / ACK were dropped, the QP will not retransmit this packet. This can lead to an application hang. Fixes: cecbcddf ("qedr: Add support for QP verbs") Signed-off-by:

Advance the qed* drivers to use firmware 8.33.1.0: Modify core driver (qed) to utilize the new FW and initialize the device with it. This is the lion's share of the patch, and includes changes to FW interface files, device initialization flows, FW interaction flows, and debug collection flows. Modify Ethernet driver (qede) to make use of new FW in fastpath. Modify RoCE/iWARP driver (qedr) to make use of new FW in fastpath. Modify FCoE driver (qedf) to make use of new FW in fastpath. Modify iSCSI driver (qedi) to make use of new FW in fastpath. Signed-off-by:

When CONFIG_IPV6 disabled, we run into a link error: drivers/infiniband/hw/qedr/qedr_iw_cm.o: In function `qedr_addr6_resolve.isra.3': qedr_iw_cm.c:(.text+0x4e0): undefined reference to `ip6_route_output_flags' The ipv6 handling code is obviously not needed here, so this adds a compile-time check for the Kconfig symbol in all three places in the code that decide between ipv4 and ipv6. We don't have to worry about a link error wtih QEDR=y/IPV6=m, as that configuration is already prohibited by CONFIG_INFINIBAND depending on "m || IPV6 != m".

Pass the second doorbell offset to userspace in create_qp response. Pbl allocation is different for RoCE and iWARP and requires different handling. RoCE allocated the pbl and passes the pointer to qed, where-as in iWARP, qed allocates the pbl and qedr populates it after it returns Signed-off-by:

There is a need to forward FW version to user space application through RDMA netlink. In order to make it safe, there is need to declare nla_policy and limit the size of FW string. The new define IB_FW_VERSION_NAME_MAX will limit the size of FW version string. That define was chosen to be equal to ETHTOOL_FWVERS_LEN, because many drivers anyway are limited by that value indirectly. The introduction of this define allows us to remove the string size from get_fw_str function signature. Signed-off-by:

Once we have iWARP support, the qede portion of the qedr<->qede would serve all the RDMA protocols - so rename the file to be appropriate to its function.
