SubjectRe: [RFC] i2c-tools: i2ctransfer: add new tool
Hi Randy,

No problem, asking questions is fine.

The thing is that this isn't only a question of maximum length. It is
also a question of which kernel interface is being used (ioctl I2C_RDWR
instead of ioctl I2C_SMBUS.) Additionally, i2ctransfer supports any
combination of reading and writing, so in essence it doesn't extend a
specific existing tool, it extends all of them. And the command line
interface will be completely different, whichever we settle for. So it
seems quite obvious that a separate tool is the best way to implement
the feature, as Wolfram did.
