[PATCH] net/ice: gate send on timestamp offload to E830

[Soumyadeep Hore]

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.
