Comment:

 -- Based on a conversation with Subir, at Marvell's QA lab. --

 The exact scenario in which this bug has been observed is as follows:

 Machines 1 to 13, all within direct range, no blinding.

 1. Start the following pings:
 {{{
 1 -> 2
 2 -> 1,3
 3 -> 1,4
 4 -> 1
 5 -> 12
 6 -> 12
 7 -> (none)
 8 -> 9
 9 -> (none)
 10 -> 9
 11 -> 8,12
 12 -> (none)
 13 -> (none)
 }}}

 2. After 12 hours, ping was failing on machines 1,2,3 and 4.  The error
 {{{
 Destination Host Unreachable
 }}}
 then
 {{{
 ping: No buffer space available
 }}}

 All were running firmware 5.220.9p10, but 5, 6, 8, 9, 11 and 12 had an
 older kernel (2.6.19) without the fix for ticket #915 (Subir was hit by
 ticket #991)

 Suggesting retest with latest kernel.
