pnp_device_id are not supposed to change at runtime. All functions working with pnp_device_id provided by <linux/pnp.h> work with const pnp_device_id. So mark the non-const structs as const. Signed-off-by:

If scsi_host_template->host_reset is NULL and the user requests an adapter reset through echo adapter > /sys/class/scsi_host/hostx/host_reset -EINVAL will be returned even though the "adapter" argument is perfectly valid. Change this so that we only return -EINVAL if the provided string is invalid. If the host does not implement a ->host_reset function we'll return -EOPNOTSUPP.

Because we were passing 'qedf_debug' instead of 'debug' to the MODULE_PARM_DESC() macro, modinfo listed the parameter name as 'qedf_debug' instead of it's proper name 'debug'. Correct the parameter name. Signed-off-by:

Currently in the driver the qedf_ctx attribute vlan_hw_insert is used to which whether to insert a VLAN tag in FIP frames (except for FIP VLAN request which is explicitly sent out untagged at least from the driver's point of view). When we receive a FIP VLAN response, we set qedf->vlan_hw_insert to 0 which makes the qedf_fip_send function insert the VLAN. However when we exhaust our FIP VLAN retries, we do not set qedf->vlan_hw_insert to 0 which means that the driver will not tag the FIP frame with the correct VLAN ID. The result that was observed on the wire is that some entity either in the LL2 or L2 firmware is adding a NULL VLAN tag which can cause FIP solicitation to fail. The offload FCoE frame function, qedf_xmit, does not use the vlan_hw_insert attribute to decide whether to tag frames with the FIP/FCoE VLAN. Instead it unilaterially tags the offload frames with the VLAN ID stored in qedf->vlan_id. This is the correct behavior so the driver can guarantee that non-offload FIP frames go out with the correct VLAN ID. Also use the Linux network layer helpers instead of doing the VLAN insert manually. Also fix setting the fallback VLAN so that it used the module parameter and is not hardcoded to 1002 (though 1002 is the default). [mkp: fixed typo] Signed-off-by:

Currently in the driver we've been using the fc_fcoe_set_mac() function to set the source MAC for FCoE traffic. This works well in most cases as it uses the spec. default FCF-MAC. However, if the administrator changes the FCF-MAC switch, then any FCoE traffic we send will be dropped by the switch. Instead we should check the granted MAC from the FLOGI payload and use that address if it is present. Otherwise, fall back to using the the default FCF-MAC and the fabric ID of the port as the FCoE MAC address. Once this address is known we need to set it when doing non-offload traffic, offload traffic and setting the data_src_address libfcoe uses for FIP keep alive messages. Signed-off-by:

The code looks like this: i = ntohl(aux->filemark_cnt); if (STp->header_cache != NULL && i < OS_FM_TAB_MAX && (i > STp->filemark_cnt || STp->first_frame_position - 1 != ntohl(STp->header_cache->dat_fm_tab.fm_tab_ent[i]))) { If i is negative then it's less than OS_FM_TAB_MAX so we read before the start of the STp->header_cache->dat_fm_tab.fm_tab_ent[] array.

Since switching to blk-mq as the default in commit 5c279bd9 ("scsi: default to scsi-mq"), virtio-scsi LUNs consume about 10x as much kernel memory. qemu currently allocates a fixed 128 entry virtqueue. can_queue currently is set to 1024. But with indirect descriptors, each command in the queue takes 1 virtqueue entry, so the number of commands which can be queued is equal to the length of the virtqueue. Note I intend to send a patch to qemu to allow the virtqueue size to be configured from the qemu command line. Signed-off-by:
