Hi, guys.
I'm learning about PCI and started looking at the bge driver.
I grepped on an error message that I found in the bge man page to find the bge
source file, but grep didn't find it in if_bge.c, but did find it in lge.c.
Is the man page incorrect for bge, or have I missed something (cluesticks,
please!)?
If it is incorrect, I'll give a go at making a patch, but just assuming at this
point that I've missed something.
bge man snippet ...
DIAGNOSTICS
(1) bge%d: can't find mem space A fatal initialization error has occurred.
(2) bge%d: couldn't map interrupt A fatal initialization error has
occurred.
(3) bge%d: no memory for jumbo buffer queue! The driver failed to allocate
memory for jumbo frames during initialization.
(4) bge%d: watchdog timeout The device has stopped responding to the
network, or there is a problem with the network connection (cable).
The numbers in parenthesis are mine, for reference.
I can see (1) and (2) in the source code, but not (3). (4) is close but not the
same - "watchdog timeout -- resetting" - in the bge source.
I'm looking at 4.8 release with patches, /usr/src/sys/dev/pci/if_bge.c (but same
list is online for 4.9)
It seems to be exactly the same diagnostics list as for lge, but I can find all
those messages in the lge source.
