TCA9548A: bus capacitance question help

I am looking to hang a TCA9548 off of an STM32 I2C bus.  I want to place 8 DRV2605L haptic drivers off of the TCA9548.  What or how do I figure out the bus capacitance in this case that loads the STM32?

Is it strictly the TCA9548 or do I have to somehow add back in the 8 drivers as well?  

The DRV2605L does not even give SDA / SCL capacitance specs?

And to make matters even more confusing the TCA9548 gives 

Thanks
