Subject: [PATCH] net/hns3: check Rx DMA address alignmnent
|
||||
|
||||
[ upstream commit d14c995b775a9b5910c51c3ab3685b320736f3f6 ]
|
||||
|
||||
The network engine has Rx DMA address align requirement, if this
|
||||
requirement is violated, the Rx function will be abnormal. The detail
|
||||
requirement is:
|
||||
1) For HIP08 platform, require 64-bytes alignment.
|
||||
2) For later platform, require 128-bytes alignment.
|
||||
|
||||
The setup Rx DMA address exists both on the control and data plane, to
|
||||
ensure performance, the alignment check is added only on the control
|
||||
plane.
|
||||
|
||||
