Jarek Januszewski Posted December 17, 2016 Share Posted December 17, 2016 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):https://sourceforge.net/projects/osx86drivers/files/Kext/Snow_or_Above/located at CLOVER/kexts/10.10 on my system's EFI partition.---Technical background (in Linux):https://tejparkash.wordpress.com/2010/03/06/tso-explained/ --- Fred says: thats all!
