Expose the active Tx burst mode and its offloads via the tx_burst_mode_get callback so applications can query how each queue sends packets. The string is derived from the Tx burst function actually installed on the device, so it reports the compact CQE path only when that path is really in use, and also lists the enabled offloads. Advertise the new capability in the feature matrix.
