Subject: bisected regression: 3c59x corrupts packets in 3.17-rc5

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
