Many low-level drivers set the fifo sizes in their attach routine, which is too late. Other drivers set them in the probe() routine, so that they're available when uart(4) allocates buffers. This fixes the ones that were setting the values too late by moving the code to probe(). Separate interrupts enable/disable logic from setting port parameters. 2012-10-30T01:52:49Z Oleksandr Tymoshenko gonzo@FreeBSD.org 2012-10-30T01:52:49Z urn:sha1:a0eae699c9abec10d158f26916fe7edcdd7f443f Otherwise setting baud rate in TTY mode effectively disables TX/RX interrupts and renders port unusable.
