When e1000e_poll() is not fast enough to keep up with incoming traffic, the adapter (when operating in msix mode) raises the Other interrupt to signal Receiver Overrun. This is a double problem because 1) at the moment e1000_msix_other() assumes that it is only called in case of Link Status Change and 2) if the condition persists, the interrupt is repeatedly raised again in quick succession. Ideally we would configure the Other interrupt to not be raised in case of receiver overrun but this doesn't seem possible on this adapter. Instead, we handle the first part of the problem by reverting to the practice of reading ICR in the other interrupt handler, like before commit |

README
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.
