Hello, I have a new Dell R740 server with BCM57416: Ethernet controller [0200]: Broadcom Limited BCM57416 NetXtreme-E 10GBase-T RDMA Ethernet Controller [14e4:16d8] (rev 01) Subsystem: Broadcom Limited BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet Controller [14e4:4160]
When I connect a cable from 100Mbps switch, everything looks good - the link LED lights up orange, data LED flashes green as when data is sent/received, this appears in log: [ 3791.655357] bnxt_en 0000:17:00.0 eno1np0: NIC Link is Up, 100 Mbps full duplex, Flow control: ON - receive & transmit [ 3791.655361] bnxt_en 0000:17:00.0 eno1np0: EEE is not active [ 3791.655364] bnxt_en 0000:17:00.0 eno1np0: FEC autoneg off encodings: None But no data comes in or out. tcpdump shows only outgoing packets and they're not transmitted in real (not seen by other machines). It works fine after connecting through a gigabit switch. Currently running 4.18.0-2-amd64 kernel (Debian testing). Any ideas? -- Ondrej Zary
