Subject: [PATCH 19/37] docs: networking: device drivers: convert dec/de4x5.txt to ReST
- add SPDX header;
- add a document title;
- mark code blocks and literals as such;
- adjust identation, whitespaces and blank lines where needed;
- add to networking/index.rst.

+DEC EtherWORKS Ethernet De4x5 cards
+===================================

Originally, this driver was written for the Digital Equipment
Corporation series of EtherWORKS Ethernet cards:
- DE425 TP/COAX EISA
- DE434 TP PCI
- DE435 TP/COAX/AUI PCI
- DE450 TP/COAX/AUI PCI
- DE500 10/100 PCI Fasternet

+ - DE435 TP/COAX/AUI PCI
+ - DE450 TP/COAX/AUI PCI
+ - DE500 10/100 PCI Fasternet
but it will now attempt to support all cards which conform to the
Digital Semiconductor SROM Specification. The driver currently
recognises the following chips:
- DC21040 (no SROM)
- DC21041[A]
- DC21140[A]
- DC21142
- DC21143
+ - DC21040 (no SROM)
+ - DC21041[A]

So far the driver is known to work with the following cards:
- KINGSTON
- Linksys
- ZNYX342
- SMC8432
- SMC9332 (w/new SROM)
- ZNYX31[45]
- ZNYX346 10/100 4 port (can act as a 10/100 bridge!)

DE434, DE435 and DE500 cards and benchmarked with 'ttcp': it transferred

All values are typical (in kBytes/sec) from a sample of 4 for each
measurement. Their error is +/-20k on a quiet (private) network and also
depend on what load the CPU has.
