Overview & identity
164f resolves to CHIP_NUM_57711 and the corresponding bnx2x PCI table entry. The source uses both Broadcom and QLogic naming; neither identifies an exact OEM board.
- Curated identifiers
pci 14e4:164f
A numeric match establishes a candidate family within the reviewed evidence. Marketing names, board variants, subsystem conditions and successful operation remain separate questions.
Driver & binding
BCM57711 follows the E1H firmware branch. The pinned implementation first requests its current E1H image and then an older revision fallback; match the actual kernel’s request, not an arbitrary file with a similar name.
bnx2x— kernel driver/module candidate
Firmware
Host-loaded firmware required
These current and fallback filenames are resolved from the pinned version constants and E1H branch. A different running kernel may request a different version; the log is the authoritative observation.
Checked examples or filename branches, not a complete installation list:
bnx2x/bnx2x-e1h-7.13.21.0.fwbnx2x/bnx2x-e1h-7.13.15.0.fw
Read-only diagnostics
Run one displayed command at a time. Replace uppercase placeholders with the affected device, interface or module from your own output. Commands are never executed here. Read-only output can still contain private identifiers.
Check the PCI function and bound driver
lspci -nnk -s BDFReplace BDF with the domain:bus:device.function address. Look for [14e4:164f] and Kernel driver in use. bnx2x in Kernel modules is only a candidate, not proof of binding.
Identify the network interface driver
ethtool -i INTERFACEReplace INTERFACE with the real interface name. Driver and bus-info connect this interface to its device. A displayed firmware-version is adapter information; it does not prove a file was loaded. Candidate: bnx2x.
Compare supported modes with the current link
ethtool INTERFACESupported/advertised link modes describe capability or negotiation offers. Speed, Duplex and Link detected describe the current link, not measured throughput. An unsupported query is a limitation of the interface/driver.
Separate PCIe transport from Ethernet speed
sudo lspci -vv -s BDFElevated access may be needed. Root can expose the full PCI configuration. If PCIe capabilities exist, compare LnkCap with LnkSta: maximum and negotiated PCIe speed/width are different from Ethernet speed. Legacy PCI or virtual functions may omit these fields.
Inspect initialization and firmware requests
sudo journalctl -k -b --no-pagerElevated access may be needed. Root reads the current boot kernel journal. Locate this controller/interface and the exact requested filename or Safe Mode message. Module-wide firmware declarations are not proof that every listed file was requested for this device.
Limitations & related issues
Board partitioning, offload settings and adapter firmware remain additional context. An available bnx2x module without successfully loaded initialization firmware is not proof of an operational network interface.
