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.

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.
