it will block other works of the list of hpwork when it waits to get buffer for too long. so use a separate workqueue for rpmsgdev.

After processing a packet of data, do not exit interrupt, but continues
to check whether there is data to be processed. If there is, continue
processing.

When using the serial framework buffer, if the buffer is full, excess
data is cached in the usb req buffer. The CDCACM driver doesn't know
when the upper layer will read data from the serial buffer, so it
needs to periodically check if the cached data can be put into the
serial buffer. However, when using zero-copy, each usb req buffer
needs to be completely read before actively switching to the next
req buffer, so the timer is not needed to assist to query.

in cdcacm_sndpacket, If `if (priv->wrcontainer)` is true, then
`priv->wrcontainer` is set to NULL. If an interrupt occurs before
`priv->wrcontainer` is reassigned after being NULL,
`priv->wrcontainer` will be reassigned once during the interrupt,
and `nwrq--` will be called, but no data will be sent at this time.
Only when data is sent by calling `txint` will `priv->wrcontainer`
be reassigned and `nwrq--` called again. This causes the issue.

When CONFIG_CDCACM_DISABLE_TXBUF is enabled, if the USB is
unplugged during serial data transmission, it is possible
that cdcacm will enter the unbind process, and reqbuf will
be released, causing a crash during serial write.

The current implementation only calls
clock_inittime() when RTC is enabled,
which causes it to be skipped on other
architectures. This patch ensures
clock_inittime() is invoked during clock

Some display drivers, like ILI9341, support 3-wire 9-bit SPI. In
contrast to 4-wire 8-bit SPI, which uses dedicated CMD/DATA pin to
distinguish between CMD and DATA, 3-wire 9-bit SPI uses MSB of 9-bit
frame for this purpose.

1. For `socket(AF_PACKET, int socket_type, int protocol)`: When `protocol` is set to `htons(ETH_P_ALL)`, then all protocols are received. If `protocol` is set to zero, no packets are received.
2. For `bind`: `bind` can optionally be called with a nonzero `sll_protocol` to start receiving packets for the protocols specified.
