The SEND_ON_TIMESTAMP TX offload capability was unconditionally advertised for all ice devices in non-safe mode. However, only E830 hardware supports TxPP (Tx Packet Pacing) via the TXTIME queue mechanism. E810 and other ice devices correctly reject the offload at queue setup time (ice_tx_queue_setup checks hw->phy_model), but advertising the capability misleads applications into thinking the feature is available.
Gate the SEND_ON_TIMESTAMP capability advertisement on hw->phy_model == ICE_PHY_E830 so that only devices which actually support TxPP report the capability.
