Subject: [PATCH 2/3] net/bnxt: avoid invalid vnic id in set L2 Rx mask
|
|
|
a6040a |
|
|
|
a6040a |
In some cases bnxt_hwrm_cfa_l2_set_rx_mask is being called before
|
|
|
a6040a |
VNICs are allocated. The FW returns an error in such cases.
|
|
|
a6040a |
Move bnxt_init_nic to bnxt_dev_init such that the ids are initialized
|
|
|
a6040a |
to an invalid id.
|
|
|
a6040a |
Prevent sending the command to the FW only with a valid vnic id.
|
|
|
a6040a |
