Somewhere between 3.17.0-rc3 and 3.17.0-rc5 I started seeing dropped ssh
connections to a couple of test servers with dual AthlonMP (32-bit) and
3C90x family of NICs (3Com Corporation 3c980-C 10/100baseTX NIC
[Python-T] (rev 78) in one server and 3Com Corporation 3c905C-TX/TX-M
[Tornado] (rev 78) in the other server). Bisect leads to the following
commit:

98ea232cf63961fad734cc8c5e07e8915ec73073 is the first bad commit
commit 98ea232cf63961fad734cc8c5e07e8915ec73073
