30717896f5 IB can't afford many RX buffers, because the MTU is so large. Reduce
the TCP window to compensate.

f3fcb53faf Don't use the mailboxless version of the HW2SW_CQ command; it seems to
crash the machine.

12b4cb964b Removed more hacks, and adjusted number of queue entries for likely usage. 2007-09-17 19:17:55 +01:00

11541b1e01 Remove hacks, and fix leaving the multicast GID. 2007-09-17 19:12:06 +01:00

267a4483ab Added an almost obscene amount of debugging and assertion code while
tracking down a bug that turned out to be a free_iob() used where I
needed a netdev_tx_complete().  This left the freed I/O buffer on the
net device's TX list, with bad, bad consequences later.

Also fixed the bug in question.

387a1a8556 Minor debug message improvement. 2007-09-17 18:57:32 +01:00
Michael Brown
2c56ede6f8 Moved iobuf.h assertions outside the static inline functions, so that
the assert message's file and line number gives some clue as to the
real location of the problem.

Added similar assertions to list.h.

b21d4ca21e Revert to dev_priv/owner_priv scheme, rather than container_of; it
makes it easier to put the generic allocation code into infiniband.c

156b409ccc Rearrange data structures to maximise embedding (and hence minimise
the number of separate allocations that need to be done).

37fc40bc8c post_recv() now works, and we can pass data on the IPoIB queue pair
using entirely our own code.
