RELENG_7_1: bce driver change generating too much interrupts ?

[Oleg Gorokhov]

This patch committed fixes the issue reported earlier with interruptions 
but there is one more problem discussed here:

http://unix.derkeiler.com/Mailing-Lists/FreeBSD/stable/2008-11/msg00144.html

We also have observed similar bad behavior for network (especially 
ssl-based) operations: imaps, ssh and smtp starttls connections - all of 
them were failed to establish after a day of successful operation:

Dec  7 23:32:41 imaps[62530]: accepted connection
Dec  7 23:32:41 imaps[62530]: SSL_accept() incomplete -> wait
Dec  7 23:32:41 imaps[62530]: wrong version number in SSL_accept() -> fail
Dec  7 23:32:41 master[3930]: process 62530 exited, status 75
Dec  7 23:32:41 master[3930]: service imaps pid 62530 in BUSY state: 
terminated abnormally

Dec  7 23:39:26 imaps[91999]: SSL_accept() incomplete -> wait
Dec  7 23:39:26 imaps[91999]: decryption failed or bad record mac in 
SSL_accept() -> fail

Dec  7 23:32:44 lmtp[77715]: [lmtpd] STARTTLS failed: gamgee.yandex.ru 
[77.88.19.54]

We have reverted back to stable before the last bce driver update was 
commited to releng branch and now hope that the system should run as 
expected.
