pk d46f710241 Enable the MII output drivers in hme_mifinit() based on the currently 
selected transceiver. Save and restore this setting in hme_mii_readreg()
and hme_mii_writereg().

pk b377c6693a Preserve the current PHY select bit in the MIF configuration register 
in mii_readreg()/mii_writereg(). Also restore this bit based on the
currently selected media instance every time we need to reinitialise
the interface.

martin 324c47457d Since we have to select one of the two possible PHYs when configuring 
the MIF Configuration Register PHY_Select, there is no use in pretending
we could talk to both at the MII interface layer.

If both PHY are reported to be present, prefer the external one.

Remember this selection and enforce it in hme_mii_{read,write}reg.
This fixes problems with one of the dual hmes in Netra T1s.

From OpenBSD.

fair 96b8b890ed Change the "dontcare bits" argument to ifmedia_init() to IFM_IMASK 
so that it is possible select PHY instances other than the first
one (instance zero), if there is more than one PHY attached.

martin 95617c00d7 Experimentation shows the hme chip is SIMPLEX if used in full-duplex 
mode, but not otherwise.

This fixes PR 17523.

thorpej 9a88d576c1 hme_init(): call mii_mediachg() to make sure the current media is set. 2002-05-05 03:02:38 +00:00
tron e75321130b Back out new "hme" driver because it causes a performance regression on 
"netio" on an U5.

tron 7287466499 Bug fixes for VLAN handling supplied by Klaus Klein in private e-mail. 2001-11-26 06:51:12 +00:00
tron 99756bfe86 Pull in Jason Wright's latest changes to the "hme" driver from OpenBSD. 
This supports direct DMA from and into mbuf cluster, and VLAN
handling is done a bit differently.

mrg c4f3ffd5e7 increase the value of _HME_NDESC from 32 to 128. it reduces the noise the 
driver makes due to various bad status conditions.

thorpej 0d4d2293bb Minor tidying up of the HME driver attach: 
- Print nicer-looking message.
- Use bus_space_subregion() when appropriate, rather than arithmetic
  on a bus_space_handle_t.

thorpej 7ca3fb9ef0 Move the check for "promisc + unicast + not for us" into ether_input(), 
and change Ethernet drivers to always pass all received frames to
ether_input() (with a few exceptions, which are documented in the
code).

mrg badbd98b2a rearrange the order of bus_dma operations to be more like many other 
drivers, at the suggestion of fvdl.  also, use bus_dmamap_load() not
load_raw().

mrg cc57e4111a do not pass a `boundary' argument to bus_dmamap_create(), particularly one 
that is smaller than the `size' argument.

thorpej fc96443d15 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

flags down from the parent to child vi mii_attach().
