The Linux kernel has changed the maximum allowed packet length per isochronous packet numerous times, which can create difficulties in trying to report appropriate errors back to the user when submitting too large of a packet on older kernels. In an attempt to improve this situation, this commit adds logic that will use different per-packet limits based on the detected kernel version. Additionally, the logic has been improved to split URBs based on the number of isochronous packets per URB, which is currently (and has been forever) limited to 128. Finally, the error reporting during URB submission has been improved to catch and report errors relating to the transfer length being too large.
