Subject: [PATCH next 0/4] Pull request for 'davem-next.r8169' branch
Please pull from branch 'davem-next.r8169' in repository
git://violet.fr.zoreil.com/romieu/linux davem-next.r8169
to get the changes below.
The series includes the remaining part of Hayes's recent patches as
well as some jumbo frames changes.
The pci_write_config_byte(pdev, 0x79, ... should be replaced with some
rtl_tx_performance_tweak variant. Feel free to peel the top-most patch
if you want me to respin it with the jumbo changes patch.
