Author: marius Date: Sun Jul 5 20:16:38 2015 New Revision: 285177 URL: https://svnweb.freebsd.org/changeset/base/285177 Log: MFC: r281337 Don't enable RX and TX before their initial configuration is done, i. e. after setting up interrupt moderation but before turning interrupts on. This matches what Realtek's r8168 Linux driver does as of version 8.039.00 and fixes problems with certain incarnations of certain MAC revisions like the interface requiring an extra up/down-cycle after boot to start working or DMA configuration not being adhered to.
