Board Compatibility - -This device driver is designed for the RealTek RTL8139 series, the RealTek -Fast Ethernet controllers for PCI and CardBus. This chip is used on many -low-end boards, sometimes with its markings changed. - - -II. Board-specific settings - -PCI bus devices are configured by the system at boot time, so no jumpers -need to be set on the board. The system BIOS will assign the -PCI INTA signal to a (preferably otherwise unused) system IRQ line. - -III. Driver operation - -IIIa. Rx Ring buffers - -The receive unit uses a single linear ring buffer rather than the more -common (and more efficient) descriptor-based architecture. Incoming frames -are sequentially stored into the Rx region, and the host copies them into -skbuffs. - -Comment: While it is theoretically possible to process many frames in place, -any delay in Rx processing would cause us to drop frames. More importantly, -the Linux protocol stack is not designed to operate in this manner. - -IIIb. Tx operation - -The RTL8139 uses a fixed set of four Tx descriptors in register space. -In a stunningly bad design choice, Tx frames must be 32 bit aligned. Linux -aligns the IP header on word boundaries, and 14 byte ethernet header means -that almost all frames will need to be copied to an alignment buffer. - -IVb.
