807331f3ef net/ice/base: fix type-mismatch
The iterators are u8, but the values being compared against are u16s.
It may not ever be the case that the comparison is against a value
larger than the upper bound of the smaller type, but code analysis tools
don't know that.

a823afa55f net/ice/base: check root pointer for validity
ice_sched_get_tc_node uses pi->root without checking for NULL. Add a
check to prevent NULL pointer dereference.

03ac4b8d11 net/ice/base: correct argument port info
correct argument pi(port_info) passed in function
ice_sched_get_first_node(), otherwise it will return the incorrect
node.

functions ice_sched_get_agg_node and ice_sched_cfg_sibl_node_prio:
change argument from hw to pi for it to align to correct port.

Moved saving tc node bw info from hardware structure(hw) to port info
structure(pi). This change allows multiple ports to save and replay
the information correctly.

dfbb0b98d4 net/ice/base: refactor zeroing bitmap size
A couple of places in the code use a 'sizeof(bitmap) * BITS_PER_BYTE'
construction to calculate the size of the bitmap when calling
ice_zero_bitmap. Instead of doing this, just use the same value as in
the ice_declare_bitmap declaration.

fdafeee39a net/ice/base: refactor VSI node scheduler
Refactored VSI node sched code to use port_info ptr as call arg.

The declaration of VSI node getter function has been modified to use
pointer to ice_port_info structure instead of pointer to hw structure.
This way suitable port_info structure is used to find VSI node.

e4b73bee79 net/ice/base: fix rate limit burst size calculation
When the MSB is not set, the lower 11 bits do not represent bytes, but
chunks of 64 bytes. Adjust the rate limit burst size calculation
accordingly, and update the comments to indicate the way the hardware
actually works.

39e30e38c4 net/ice/base: add sibling head to parse nodes
There was a bug in the previous code which never traverses all the
children to get the first node of the requested layer.

Added a sibling head pointer to point the first node of each layer
per TC. This helps the traverse easy and quicker and also removed the
recursive, complexity of the code.

1b969112dc net/ice/base: save queue bandwidth for replay after reset
Added code to save the queue bandwidth information when it is applied
and it is replayed when queue is re-enabled again. Earlier saved value
is used for replay purpose.
Added vsi_handle, tc, and q_handle argument to the ice_cfg_q_bw_lmt,
ice_cfg_q_bw_dflt_lmt.
