The ice_alloc_lan_q_ctx function allocates the queue context array for a
given traffic class. This function uses devm_kcalloc which will
zero-allocate the structure. Thus, prior to any queue being setup by
ice_ena_vsi_txq, the q_ctx structure will have a q_handle of 0 and a q_teid
of 0. These are potentially valid values.
Modify the ice_alloc_lan_q_ctx function to initialize every member of the
q_ctx array to have invalid values. Modify ice_dis_vsi_txq to ensure that
it assigns q_teid to an invalid value when it assigns q_handle to the
invalid value as well.
This will allow other code to check whether the queue context is currently
valid before operating on it.

The code implicitly assumes that the list iterator finds a correct

pointing to an bogus memory location. For safety a separate list
iterator variable should be used to make the != NULL check on
'old_agg_vsi_info' correct under any circumstances.
Additionally Linus proposed to avoid any use of the list iterator
variable after the loop, in the attempt to move the list iterator
variable declaration into the macro to avoid any potential misuse after
the loop. Using it in a pointer comparison after the loop is undefined
behavior and should be omitted if possible [1].

the RDMA Tx queue scheduler node configuration will not be cleaned up.
This will cause the rebuild/re-add of the VSI to fail due to the

Fix this by always calling ice_rm_vsi_rdma_cfg() for all VSI. If there
are no RDMA scheduler nodes created, then there is no harm in calling
ice_rm_vsi_rdma_cfg(). This change applies to all VSI types, so if

Distribute the Tx queues evenly across all queue groups. This will
help the queues to get more equal sharing among the queues when all
are in use.
In the previous algorithm, the next queue group node will be picked up
only after the previous one filled with max children.
For example: if VSI is configured with 9 queues, the first 8 queues
will be assigned to queue group 1 and the 9th queue will be assigned to
queue group 2.
The 2 queue groups split the bandwidth between them equally (50:50).
The first queue group node will share the 50% bandwidth with all of
its children (8 queues). And the second queue group node will share
the entire 50% bandwidth with its only children.
The new algorithm will fix this issue.

the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = alloc(size, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
size = struct_size(instance, entry, count);

This patch adds a new function ice_pf_dcb_cfg (and related helpers)
which applies the DCB configuration obtained from the firmware. As
part of this, VSIs/netdevs are updated with traffic class information.
This patch requires a bit of a refactor of existing code.
1. For a MIB change event, the associated VSI is closed and brought up
again. The gap between closing and opening the VSI can cause a race
condition. Fix this by grabbing the rtnl_lock prior to closing the
VSI and then only free it after re-opening the VSI during a MIB
change event.
2. ice_sched_query_elem is used in ice_sched.c and with this patch, in
ice_dcb.c as well. However, ice_dcb.c is not built when CONFIG_DCB is
unset. This results in namespace warnings (ice_sched.o: Externally
defined symbols with no external references) when CONFIG_DCB is unset.
To avoid this move ice_sched_query_elem from ice_sched.c to
ice_common.c.
