go_bridge.h's CGpuTx has max_fee_per_gas and max_priority_fee_per_gas in place of gas_price, 120 bytes on LP64. Transaction has GasFeeCap and GasTipCap for them, both the gas price of a legacy or access-list tx, and buildTxs sets both; the size check reads 120. cevm charges min(cap, base fee + tip), as the EVM does, and declines a tip above the cap, which the device test sends.
