If qed_mcp_send_drv_version() fails, no cleanup is executed, leading to
memory leaks. To fix this issue, introduce the label 'err4' to perform the

strncpy() does not ensure NULL-termination when the input string
size equals to the destination buffer size 30.
The output string is passed to qed_int_deassertion_aeu_bit()
which calls DP_INFO() and relies NULL-termination.

Use strlcpy instead. The other conditional branch above strncpy()
needs no fix as snprintf() ensures NULL-termination.

This issue is identified by a Coccinelle script.

VFs may hit VF-PF channel timeout while probing, as in some
cases it was observed that VF FLR and VF "acquire" message
transaction (i.e first message from VF to PF in VF's probe flow)
could occur simultaneously which could lead VF to fail sending
"acquire" message to PF as VF is marked disabled from HW perspective
due to FLR, which will result into channel timeout and VF probe failure.

In such cases, try retrying VF "acquire" message so that in later
attempts it could be successful to pass message to PF after the VF
FLR is completed and can be probed successfully.

When running tx switched traffic between VNICs
created via a bridge(to which VFs are added),
adapter drops the unicast packets in tx flow due to
VNIC's ucast mac being unknown to it. But VF interfaces
being in promiscuous mode should have caused adapter
to accept all the unknown ucast packets. Later, it
was found that driver doesn't really configure tx
promiscuous mode settings to accept all unknown unicast macs.

This patch fixes tx promiscuous mode settings to accept all
unknown/unmatched unicast macs and works out the scenario.

The getter callers doesn't know the valid Physical Queues (PQ) values.
This patch makes sure that a valid PQ will always be returned.

The patch consists of 3 fixes:

 - When qed_init_qm_get_idx_from_flags() receives a disabled flag, it
   returned PQ 0, which can potentially be another function's pq. Verify
   that flag is enabled, otherwise return default start_pq.

 - When qed_init_qm_get_idx_from_flags() receives an unknown flag, it
   returned NULL and could lead to a segmentation fault. Return default
   start_pq instead.

 - A modulo operation was added to MCOS/VFS PQ getters to make sure the
   PQ returned is in range of the required flag.

Certain flows need to access the rdma-info structure, for example dcbx
update flows. In some cases there can be a race between the allocation or
deallocation of the structure which was done in roce start / roce stop and
an asynchrounous dcbx event that tries to access the structure.
For this reason, we move the allocation of the rdma_info structure to be
similar to the iscsi/fcoe info structures which are allocated during device
setup.
We add a new field of "active" to the struct to define whether roce has
already been started or not, and this is checked instead of whether the
pointer to the info structure.

This has been here since commit 1fe614d1 ("qed: Relax VF firmware
requirements") and I am not entirely sure why since 0 isn't a special
case. Just remove the statement causing Clang to warn since it isn't
required.

Use the appropriate values from the expected type, roce_flavor:

ROCE_V2_IPV6 = RROCE_IPV6 = 2
MAX_ROCE_MODE = MAX_ROCE_FLAVOR = 3

While we're add it, ditch the local variable flavor, we can just return
the value directly from the switch statement.

Avoid this by changing type to an int.

In certain multi-function switch dependent modes, firmware adds vlan tag 0
to the untagged frames. This leads to double tagging for the traffic
if the dcbx is enabled, which is not the desired behavior. To avoid this,
driver needs to set "dcb_dont_add_vlan0" flag.

In multi-function mode, driver receives the stag value (outer vlan)
for a PF from management FW (MFW). If the stag value is negotiated prior to
the driver load, then the stag is not notified to the driver and hence
driver will have the invalid stag value.
The fix is to request the MFW for STAG value during the driver load time.
