One card queue is smaller than the other one. As I see there is a lot of traffic on the interface so, the lower queue size is dropping packets as he has not room for them. This is a usual problem that I saw mostly when connection an old card to a new server which support a high throughput and is having a lot of traffic. In my case the solution was to replace the hardware.
Maybe somebody has a different approach for this issue?
Input queue drops usually indicate the device couldn't process the input stream fast enough, and sometimes requires analysis and effort to elminate.
Output queue drops usually indicate (transient) congestion, and for such, is quite normal.
Since you only had 33 input drops for 35,908,851 packets input, it shouldn't be of concern.
You had 58,350 output drops for 35,645,315 packets output, which isn't real bad at about .16%. For gig speed on a LAN, and allowing for a BDP based on about 1 ms latency, you could pretty safely double your output queue size to 80 and see if that decreases your drop percentage.
