From 51450d769a6633b1051f2dc8618485face1c028c Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Thu, 18 Feb 1999 20:58:13 +0000 Subject: Added NE2000 Driver from Ian Lance Taylor . Comments: Both the ne2000 and the wd80x3 are based on the National Semiconductor 8390 chip, so there is a fair amount of overlap between the two drivers. It would be possible in principle to combine some code into a separate set of subroutines called by both. In fact, the drivers in both OpenBSD and Linux work this way. I didn't bother, because for the relatively simple drivers used by RTEMS, the overlap is not especially large, and any reasonable use of subroutines would lead to slightly less efficient code. This ne2000 driver uses two transmit buffers. While one packet is being transmitted over the Ethernet, RTEMS will upload another. Since uploading a packet to the ne2000 is rather slow, I don't think there is any point to having more than two transmit buffers. However, the code does make it possible, by changing NE_TX_BUFS, although that would of course reduce the number of receive buffers. I suspect that the wd80x3 driver would benefit slightly from copying the multiple transmit buffer code. However, I have no way to test that. --- c/src/lib/libbsp/i386/pc386/Makefile.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'c/src/lib/libbsp/i386/pc386/Makefile.in') diff --git a/c/src/lib/libbsp/i386/pc386/Makefile.in b/c/src/lib/libbsp/i386/pc386/Makefile.in index c615540a60..d10dbee0e9 100644 --- a/c/src/lib/libbsp/i386/pc386/Makefile.in +++ b/c/src/lib/libbsp/i386/pc386/Makefile.in @@ -14,7 +14,7 @@ include $(RTEMS_ROOT)/make/custom/$(RTEMS_BSP).cfg include $(RTEMS_ROOT)/make/directory.cfg # We only build the Network library if HAS_NETWORKING was defined -NETWORK_yes_V = network +NETWORK_yes_V = network ne2000 NETWORK = $(NETWORK_$(HAS_NETWORKING)_V) # wrapup is the one that actually builds and installs the library -- cgit v1.2.3
