thorpej | Define and implement a locking protocol for the ifmedia / mii layers:
- MP-safe drivers provide a mutex to ifmedia that is used to serialize
access to media-related structures / hardware regsiters. Converted
drivers use the new ifmedia_init_with_lock() function for this. The
new name is provided to ease the transition.
- Un-converted drivers continue to call ifmedia_init(), which will supply
a compatibility lock to be used instead. Several media-related entry
points must be aware of this compatibility lock, and are able to acquire
it recursively a limited number of times, if needed. This is a SPIN
mutex with priority IPL_NET.
- This same lock is used to serialize access to PHY registers and other
MII-related data structures.
The PHY drivers are modified to acquire and release the lock, as needed,
and assert the lock is held as a diagnostic aid.
The "usbnet" framework has had an overhaul of its internal locking
protocols to fit in with the media / mii changes, and the drivers adapted.
USB wifi drivers have been changed to provide their own adaptive mutex
to the ifmedia later via a new ieee80211_media_init_with_lock() function.
This is required because the USB drivers need an adaptive mutex.
Besised "usbnet", a few other drivers are converted: vmx, wm, ixgbe / ixv.
mcx also now calls ifmedia_init_with_lock() because it needs to also use
an adaptive mutex. The mcx driver still needs to be fully converted to
NET_MPSAFE.

msaitoh | - Simplify sc->mii_anegticks setting. Same as FreeBSD.
Don't set the default value not in the attach function. Instead, set the
default value (MII_ANEGTICKS) first in the beginning of the
mii_phy_add_media(). The function already has the code to change the value to
MII_ANEGTICKS_GIGE if it's gigabit capable.
- Remove extra pmf_device_register() call. It's done in mii_phy_add_media().

christos | use a macro to tidy up the phydesc array initialization, from FreeBSD
|
| 1.22 |
| 22-Jan-2019 |
msaitoh | Change MII PHY read/write API from:
int (*mii_readreg_t)(device_t, int, int);
void (*mii_writereg_t)(device_t, int, int, int);
to:
int (*mii_readreg_t)(device_t, int, int, uint16_t *);
int (*mii_writereg_t)(device_t, int, int, uint16_t);
Now we can test if a read/write operation failed or not by the return value.
In 802.3 spec says that the PHY shall not respond to read/write transaction
to the unimplemented register(22.2.4.3). Detecting timeout can be used to
check whether a register is implemented or not (if the register conforms to
the spec). ukphy(4) can be used this for MII_MMDACR and MII_MMDAADR.
Note that I noticed that the following code do infinite loop in the
read/wirte function. If it accesses unimplemented PHY register, it will hang.
It should be fixed:
