Packets dropped
While using this version of the driver I noticed there was a high number of packets dropped using Fedora 29. I was transferring about 70 gig worth of data via SMB and noticed over 429k packets were dropped before I ended the transfer and reverted to the kernel's driver implementation. This is using kernel 5.0.5-200.fc29.x86_64 and an Asus XG-C100C(Atlantic 107). Reverting to the kernels implementation I lost about 1 MB/s in through put but there were no dropped packets. This card is currently connected at a 1Gbs link. I have hardware arriving that will enable the card to run at full speed. It is connected to a Cisco SG300 52-52 using Cat5E
Interesting I noticed that on f29 to ubuntu bionic I was getting autoneg failures and when it did negotiate it would only do so at 100mb - forcing the speed to 10000 fixed when I upgraded the ubuntu side kernel to a mainline 4.20.17 kernel.
Previously ubuntu to ubuntu was working without issue. what firmware does ethtool report for you on the card?

@ldhasty, how did you checked the number of drops?
Could you provide the following output before and after the transfer In good and bad cases:
ethtool -S enp1s0
@cail I used ifconfig here is the output Stock Driver

in kernel driver did not reported "dropped" counter. Thats why you don't see it increasing. I guess its always increasing, in both drivers. You may check in kernel driver ethtool -S, line InDroppedDma: 656988 will show you actual drops. Guess it'll be non zero.
Drops are inevitable on high rates, especially with udp-based protocols.
