2018-09-29qlcnic: fix Tx descriptor corruption on 82xx devicesShahed Shaikh1-1/+2
In regular NIC transmission flow, driver always configures MAC using Tx queue zero descriptor as a part of MAC learning flow. But with multi Tx queue supported NIC, regular transmission can occur on any non-zero Tx queue and from that context it uses Tx queue zero descriptor to configure MAC, at the same time TX queue zero could be used by another CPU for regular transmission which could lead to Tx queue zero descriptor corruption and cause FW abort. This patch fixes this in such a way that driver always configures learned MAC address from the same Tx queue which is used for regular transmission.

2015-08-10qlcnic: Add support to enable capability to extend minidump for iSCSIShahed Shaikh1-0/+1
In some cases it is required to capture minidump for iSCSI functions as part of default minidump collection process. To enable this, firmware exports it's capability and driver need to enable that capability by issuing a mailbox command. With this feature, firmware can provide additional iSCSI function's minidump with smaller minidump capture mask (0x1f). Signed-off-by: Shahed Shaikh <shahed.shaikh@qlogic.com> Signed-off-by: David S.

2013-03-29qlcnic: VF-PF communication channel implementationRajesh Borundia1-0/+2
o Adapter provides communication channel between VF and PF. Any control commands from the VF driver are sent to the PF driver through this communication channel. PF driver validates the commands before sending them to the adapter. Similarly PF driver forwards any control command responses to the VF driver through this communication channel. Adapter sends message pending event to VF or PF when there is an outstanding response or a command for VF or PF respectively. When a command or a response is sent over a channel VF or PF cannot send another command or a response until adapter sends a channel free event. Adapter allocates 1K area to VF and PF each for this communication. o Commands and responses are encapsulated in a header. Header determines sequence id, number of fragments, fragment number etc. Signed-off-by: Manish Chopra <manish.chopra@qlogic.com> Signed-off-by: Sucheta Chakraborty <sucheta.chakraborty@qlogic.com> Signed-off-by: Rajesh Borundia <rajesh.borundia@qlogic.com> Signed-off-by: David S.
