/* achu & hliebig:
*
* Premise from ipmitool (http://ipmitool.sourceforge.net/)
*
* On some OSes (it seems Unixes), the behavior is to not return
* port denied errors up to the client for UDP responses (i.e. you
* need to timeout). But on some OSes (it seems Windows), the
* behavior is to return port denied errors up to the user for UDP
* responses via ECONNRESET or ECONNREFUSED.
*
* If this were just the case, we could return or handle errors
* properly and move on. However, it's not the case.
*
* According to Ipmitool, on some motherboards, both the OS and the
* BMC are capable of responding to an IPMI request. That means you
* can get an ECONNRESET or ECONNREFUSED, then later on, get your
* real IPMI response.
*
* Our solution is copied from Ipmitool, we'll ignore some specific
* errors and try to read again.
*
* If the ECONNREFUSED or ECONNRESET is from the OS, but we will get
* an IPMI response later, the recvfrom later on gets the packet we
* want.
*
* If the ECONNREFUSED or ECONNRESET is from the OS but there is no
* BMC (or IPMI disabled, etc.), just do the recvfrom again to
* eventually get a timeout, which is the behavior we'd like.
