[Bug Description]
A single transmit packet can span up to 8 descriptors,
TSO transmit packet can be stored up to 63 descriptors
and each segment within the TSO should be spanned up to
8 descriptors.
If the packet needs more than 8 BD, and the total size of
every 7 continuous frags more than MSS, HW does not support
it, and it need driver makes SKB Linearized.
[Actual Results]
iscsi and bigdata spark test OK
[Expected Results]
iscsi and bigdata spark test OK
[Reproducibility]
Inevitably

51e8439f3496 net: hns3: add 8 BD limit for tx flow
5f543a54eec0 net: hns3: fix for not calculating tx bd num correctly |
[Impact]
We get reports that iscsi and spark tests fail on hns3
[Fix]
Cherry-pick/backport patches from upstream.
net: hns3: add 8 BD limit for tx flow
net: hns3: avoid mult + div op in critical data path
net: hns3: remove some ops in struct hns3_nic_ops
net: hns3: fix for not calculating tx bd num correctly
net: hns3: unify maybe_stop_tx for TSO and non-TSO case
net: hns3: add check for max TX BD num for tso and non-tso case
net: hns3: fix for TX queue not restarted problem
net: hns3: fix a use after free problem in hns3_nic_maybe_stop_tx()
[Test]
No known way to reproduce it in our lab. Regression test only.
[Regression Potential]
Patchset only affects hns3 driver. Minimal risk for other drivers and platform.
