0006758: tg3 drivers

The TG3 drivers for Dell SC1435's on kernel 2.6.32-358.23.2.el6.x86_64 seems to run with pause frames, causing our connection to become unstable. This also happens with ELRepo's kmod-tg3 module and the latest CentOS kernel release.<br /> <br /> I am having connectivity issues with this update, but when I rolled back to kernel 2.6.32-71.el6.x86_64, everything seems to work fine with tg3 again.<br /> <br /> (With kernel 2.6.32-358.23.2.el6.x86_64)<br /> # modinfo tg3<br /> filename: /lib/modules/2.6.32-358.23.2.el6.x86_64/weak-updates/tg3/tg3.ko<br /> firmware: tigon/tg3_tso5.bin<br /> firmware: tigon/tg3_tso.bin<br /> firmware: tigon/tg3.bin<br /> version: 3.133d<br /> license: GPL<br /> description: Broadcom Tigon3 ethernet driver<br /> author: David S.
