This patch adds sysfs node 1. There is a new sysfs node port_speed 2. The possible values are 2(Auto neg), 8, 16, 32 3. A value outside of the above defaults to Auto neg 4. Any update to the setting causes a link toggle 5.

Add ability to allow each physical port to control operating mode. Current code forces all ports to behave in one mode (i.e. initiator, target or dual). This patch allows user to select the operating mode for each port. - Driver must be loaded in dual mode to allow resource allocation modprobe qla2xxx qlini_mode=dual - In addition user can make adjustment to exchange resources using following command echo 1024 > /sys/class/scsi_host/host<x>/ql2xiniexchg echo 1024 > /sys/class/scsi_host/host<x>/ql2xexchoffld - trigger mode change and new setting of ql2xexchoffld|ql2xiniexchg echo [<value>] > /sys/class/scsi_host/host<x>/qlini_mode where, value can be one of following - enabled - disabled - dual - exclusive Signed-off-by: NQuinn Tran <quinn.tran@cavium.com> Signed-off-by: NHimanshu Madhani <himanshu.madhani@cavium.com> Signed-off-by: NMartin K.

Using GPNFT/GNNFT command will be able to cover switch database with less number of scans. This patch removes Get NportID with provided WWPN/GIDPN switch command. By making this change, in large fabric with lots of remote port or NPIV ports with noisy SAN, the number of GIDPN commands issued by a port when it detects large number of remote ports going away or coming back, can overwhelmn the switch and it can becomde unresponsive. In a case where the fabric has not change, GIDPN is not required.

Currently, the rport registration is being called from a single work element that is used to process QLA internal "work_list". This work_list is meant for quick and simple task (ie no sleep). The Rport registration process sometime can be delayed by upper layer. This causes back pressure with the internal queue where other jobs are unable to move forward. This patch will schedule the registration process with a new work element (fc_port.reg_work). While the RPort is being registered, the current state of the fcport will not move forward until the registration is done. If the state of the fabric has changed, a new field/next_disc_state will record the next action on whether to 'DELETE' or 'Reverify the session/ADISC'.

Added logic to change the login process into an optional PRIL step for FC-NVMe ports as a separate operation, such that we can change type to 0x28 (NVMe). Currently, the driver performs the PLOGI/PRLI together as one operation, but if the discovered port is an NVMe port then we first issue the PLOGI and then we issue the PRLI. Also, the fabric discovery logic was changed to mark each discovered FC NVMe port, so that we can register them with the FC-NVMe transport later.

Previously, the ql2xexchoffld module parameter was used to control the max number of exchanges to be offload onto host memory. Module parameter ql_dm_tgt_ex_pct was used to control the percentage of exchanges allocated to the Target side. With this patch, module parameter ql_dm_tgt_ex_pct is no longer used to control exchanges for the driver. New module parameter ql2xiniexchg is added to control exchanges between target mode and initiator mode. With the updated module parameters, users can control the exact number of exchanges for either Initiator or Target. The exchange offload feature will be automatically enabled when the total number of exchanges exceeds 2048 limit.
