Use the new pci_bandwidth_available() function to calculate maximum available bandwidth through the PCI chain instead of computing it ourselves with mlx5e_get_pci_bw(). This is used to detect when the device is capable of more bandwidth than is available in the current slot. The driver may adjust compression settings accordingly. Note that pci_bandwidth_available() accounts for PCIe encoding overhead, so it is more accurate than mlx5e_get_pci_bw() was.

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.
