When USB Ethernet is plugged in ASMEDIA ASM1042A xHCI host, bad performance was manifesting in Web browser use (like download large file such as ISO image). It is known limitation of ASM1042A that is not compatible with driver scheduling, As a workaround we can modify flow control handling of ASM1042A. The register we modify is changes the behavior [use quirk bit 28, usleep_range 40-60us, empty non-pci function -Mathias] Cc: <stable@vger.kernel.org> Signed-off-by: Jiahau Chang <Lars_chang@asmedia.com.tw> Signed-off-by: Ian Pilcher <arequipeno@gmail.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
