Move dtbs install rules to Makefile.dtbinst. This change is needed to
implement support for dts vendor subdirs. The change makes Makefiles
easier and smaller as no longer the dtbs_install rule needs to be

I2C_CLKDIV register descripted in the previous version of
RK3x chip manual is incorrect. Plus 1 is required.
The correct formula:
- T(SCL_HIGH) = T(PCLK) * (CLKDIVH + 1) * 8
- T(SCL_LOW) = T(PCLK) * (CLKDIVL + 1) * 8
- (SCL Divsor) = 8 * ((CLKDIVL + 1) + (CLKDIVH + 1))
- SCL = PCLK / (CLK Divsor)

Ah yes, I stand corrected. According to Wikipedia, the affected CPUs
were all the 2106x CPUs (EV4, EV45, LCA4, LCA45) plus the 2116

Selftest is an important part of network driver, this patch adds
selftest for
virtio-net, including loopback test, negotiate test and reset test. Loopback
test checks whether virtio-net can send and receive packets normally. Negotiate
test
executes feature negotiation between virtio-net

In tg3_set_ringparam(), the tx_pending test to cover the cases where
tg3_tso_bug() is entered has two problems
1) the check is only done for certain hardware whereas the workaround
is now used more broadly. IOW, the check may not be performed when it
is needed.
2) the check is too optimistic.
