Description

Broadcom GENET Gigabit Ethernet Driver unit

This driver supports members of the Broadcom family of Gigabit Ethernet devices including the BCM54213PE contained in the Raspberry Pi 4B.

These devices support speeds of 10BASE-T, 100BASE-TX and 1000BASE-T and include a range of features including WOL and EEE.

The device included in the Raspberry Pi 4B uses a memory mapped interface which supports multiple TX and RX queues with priority queueing, hardware filtering and DMA bus master transfers.
