Patient: Intel i350 ethernet built into Supermicro X9DAi motherboard.

Symptoms: constant disconnects on upload (files to FTP / sending emails w. attachments / using services like dropbox or wetransfer / browser uploads / ... ), so only restart helps.

 

Treatment: edit info.plist of AppleIGB.kext (wherever u use it) and change the NETIF_F_TSO key under i350 dictionary to false:

        <key>i350</key>
        <dict>
            <key>CFBundleIdentifier</key>
            <string>com.insanelymac.driver.AppleIGB</string>
            <key>IOClass</key>
            <string>AppleIGB</string>
            <key>IOPCIMatch</key>
            <string>0x15218086</string>
            <key>IOProviderClass</key>
            <string>IOPCIDevice</string>
            <key>NETIF_F_TSO</key>
            <false/>
        </dict>

Restart your machine and enjoy full power of your ethernet never ever crashing on large packet upload.

FYI I use hnak's AppleIGB kext (5.3.5):

located at CLOVER/kexts/10.10 on my system's EFI partition.
