- PCH only: Add workaround for link disconnects on a busy hub in half duplex.
- PCH and PCH2 only: Set MSE higher to enable link to stay up when noise is
high.
- PCH2 only: Drop link after 5 times MSE threshold was reached.
- PCH2 only: Set EEE LPI Update Timer to 200usec.
- For PCH2 and newer: When connected at 10Mbps half-duplex, some parts are
excessively aggressive resulting in many collisions. To avoid this, increase
the IPG and reduce Rx latency in the PHY.
- For I21[789] and if EEE is enabled: Disable LPLU if both link partners
support 100BaseT EEE and 100Full is advertised on both ends of the link, and
enable Auto Enable LPI since there will be no driver to enable LPI while in
Sx.
- Rename wm_smbustopci() to wm_init_phy_workarounds_pchlan(). It will also
called when resume.
- Call wm_phy_resetisblocked() after PHY reset in
wm_init_phy_workarounds_pchlan() to wait for the PHY to quiesce to an
accessible state.
- Add new wm_resume_workarounds_pchlan() function and use it in wm_resume().
This workaround is only for PCH2 and newer.
- Don't call wm_disable_aspm() neither in wm_attach() nor in wm_resume()
but in wm_reset().
- Do some initialization in wm_resume() when IFF_UP is NOT set.
- Don't continue when it failed to acquire semaphore in wm_ulp_disable().
- Add comment.
Workaround to set the K1 beacon duration for 82579 parts in 10Mbps.
Disable K1 for 1000 and 100 speeds.
- Make wm_link_stall_workaround_hv() and move an 82578 specific code into it.
Don't apply the workaround if BMCR_LOOP bit is set. Same as FreeBSD.
- Add comment. Modify comment.
PCH_LPT with I218. Same as FreeBSD and Linux. This woraround is only for
device ID 0x155a, 0x15a2, 0x1559 and 0x15a3. I observed this problem on my
Shuttle DS57U's I218 port six times in two months.
wm_linkintr_gmii().
- Register access in wm_kmrn_lock_loss_workaround_ich8lan() now works
correctly. Enable this function.
- Configure the LCD with the extended configuration region in NVM if it's
required.
- Add debug printf.
