[PATCH V2 net-next 1/6] net: hns3: add api capability bits for firmware

[Huazhong Tan]

From: Jian Shen <shenjian15@huawei.com>

To improve the compatibility of firmware for driver, help firmware
to deal with different api commands, add api capability bits when
initialize the command queue.

[PATCH V2 net-next 2/6] net: hns3: RSS indirection table use device specification

[Huazhong Tan]

From: Guangbin Huang <huangguangbin2@huawei.com>

As RSS indirection table size may be different in different
hardware. Instead of using macro, this value is better to use
device specification which querying from firmware.

BTW, RSS indirection table should be allocated by the queried
size instead the static array.

.get_rss_indir_size in struct hnae3_ae_ops is not used now,
so remove it as well.

[PATCH V2 net-next 3/6] net: hns3: optimize the code when update the tc info

[Huazhong Tan]

From: GuoJia Liao <liaoguojia@huawei.com>

When update the TC info for NIC, there are some differences
between PF and VF. Currently, four "vport->vport_id" are
used to distinguish PF or VF. So merge them into one to
improve readability and maintainability of code.

[PATCH V2 net-next 4/6] net: hns3: add support for obtaining the maximum frame size

[Huazhong Tan]

From: Yufeng Mo <moyufeng@huawei.com>

Since the newer hardware may supports different frame size,
so add support to obtain the capability from the firmware
instead of the fixed value.

[PATCH V2 net-next 6/6] net: hns3: replace macro of max qset number with specification

[Huazhong Tan]

From: Guangbin Huang <huangguangbin2@huawei.com>

The max qset number is a fixed value now and it is defined by a macro.
In order to support other value in different kinds of device, it is
better to use specification queried from firmware to replace macro.
