[PATCH v3 07/32] net/sssnic/base: add mailbox support

[wanry]

From: Renyong Wan 

Mailbox is a message channel used to communicate between PF and
VF as well as driver and hardware functions.
Mailbox messages are received by driver through event queue, and
sent by driver through registers of mailbox.
There are two transfer modes for sending mailbox message, one is
DMA mode used to send message to PF, another is inline mode used
to send message to VF.

[PATCH v3 06/32] net/sssnic/base: add message definition and utility

[wanry]

From: Renyong Wan 

sssnic message is used to encapsulate sssnic command for transmission
between driver and firmware. sssnic message is sent by driver via mail
box and is received by driver via event queue.

[PATCH v4 07/32] net/sssnic/base: add mailbox support

[wanry]

From: Renyong Wan 

Mailbox is a message channel used to communicate between PF and
VF as well as driver and hardware functions.
Mailbox messages are received by driver through event queue, and
sent by driver through registers of mailbox.
There are two transfer modes for sending mailbox message, one is
DMA mode used to send message to PF, another is inline mode used
to send message to VF.

[PATCH v5 07/32] net/sssnic/base: add mailbox support

[wanry]

From: Renyong Wan 

Mailbox is a message channel used to communicate between PF and
VF as well as driver and hardware functions.
Mailbox messages are received by driver through event queue, and
sent by driver through registers of mailbox.
There are two transfer modes for sending mailbox message, one is
DMA mode used to send message to PF, another is inline mode used
to send message to VF.
