6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: David Arinzon <darinzon@xxxxxxxxxx> [ Upstream commit 39a044f4dcfee1c776603a6589b6fb98a9e222f2 ] This change will enable the ability to use ena_xmit_common() in functions that don't have a net_device pointer. While it can be retrieved by dereferencing ena_adapter (adapter->netdev), there's no reason to do it in fast path code where this pointer is only needed for debug prints.
