When sending a big fragment using multiple buffer descriptor,
hns3 does one maping, but do multiple unmapping when tx is done,
which may cause unmapping problem.

To fix it, this patch makes sure the value of desc_cb.length of
the non-first bd is zero. If desc_cb.length is zero, we do not
unmap the buffer.

So far all the places calling hclge_tm_q_to_qs_map_cfg() are assigning
an u16 type value to "q_id", and in the processing of
hclge_tm_q_to_qs_map_cfg(), it also converts the "q_id" to le16.

The max tqp number for pf can be more than 256, we should use "u16" to
store the queue id, instead of "u8", which may cause data lost.

net: hns3: Fix client initialize state issue when roce client initialize failed

BugLink: https://bugs.launchpad.net/bugs/1810457
When roce is loaded before nic, the roce client will not be initialized
until nic client is initialized, but roce init flag is set before it.
Furthermore, in this case of nic initialized success and roce failed,
the nic init flag is not set, and roce init flag is not cleared.

This patch fixes it by set init flag only after the client is initialized
successfully.

is using ethtool to setting the speed of phy and service task is calling

Because ethtool cmd will modified phydev and hclge_get_mac_phy_link also
will modified phydev.

Because phy state machine will update phy link periodically, we can
just use phydev->link to check the link status. This patch removes
function call of genphy_read_status. To ensure accuracy, this patch
adds a phy state check. If phy state is not PHY_RUNNING, we consider
link is down. Because in some scenarios, phydev->link may be link up,
but phy state is not PHY_RUNNING. This is just an intermediate state.
